WELCOME FROM THE

GENERAL CHAIR

L U Í S M. C O R R E I A

elcome to the 2017 edition of ISMICT, the 11th International Symposium on Medical Information and Communication Technology, which we have the pleasure to host in Lisbon, Portugal.

Dependable Medicine using advanced Information and Communication Technology (ICT) based on Regulatory Science (RS) is the focus of this year’s edition. ISMICT aims to establish a forum to present new research and development results, exchange ideas, discuss practices, and share experiences among Technology and Medicine sides including healthcare, wellness, clinical therapy, and surgery as well as ICT, mechanical, and biomedical engineering. Moreover, activities of standard, regulation, and business for medical ICT devices, systems and services will be promoted by national, European, and global government and industry.

This year’s program follows the structure of the previous ones. We’ve a well-balanced mixture of Keynotes, Panel, Workshop and regular paper presentations, in a single track, creating the conditions for a very fruitful discussion and exchange of ideas.

Lisbon, the westernmost city in continental Europe, is quite an attractive place to visit, and you can easily extend your stay for a few days, so that you can enjoy the city and its surroundings, as well as its gastronomy. The weather is usually quite mild, and you’ll be experiencing a pleasant almost Spring in the region.

My personal wishes that you enjoy both the conference and the city. Thank you for coming.

WELCOME TO LISBON

elcome to Lisbon! Lisbon is the capital of Portugal lying on the north bank of the Tagus River, on the European Atlantic coast. It is the westernmost capital city in continental Europe, a crossroad between North and South, East and West.

Lisbon is Europe's second-oldest capital (after Athens), once home to the world's greatest explorers like Vasco da Gama, Magellan and Prince Henry the Navigator, becoming the first true world city, the capital of an empire spreading over all continents, from South America (Brazil) to Asia (Macao, China; Goa, India). The former launch pad for many of the world's greatest voyages is now where modern travelers discover.

Lisbon is one of the most attractive cities in Europe, an ideal place to combine a professional meeting with a break for leisure activities.

Visited by many peoples along the millennia of its long history Lisbon has captured the influence of many cultures and combined them into a potpourri of unusual character and charm, which mingle with modern trends and life styles creating spectacular contrasts.

Lisbon is recognized ever since as the city of seven hills, characterized by the existence of very winding and steep streets, which hinder pedestrian movement and mobility. It was with this in mind funiculars lift services were started, consisting today of historical means of transport, classified as National Monuments. Do a tour around Lisbon, visiting its traditional funiculars with magnificent views of the city, and surrounding museums. For more information, visit: www.visitlisboa.com.

SYMPOSIUM VENUE

GENERAL INFORMATION

The meeting will take place at Instituto Superior Técnico (IST) – University of Lisbon, Alameda campus in Lisbon, at Av. Rovisco Pais, 1049-001 Lisbon. The whole meeting will take place at the Congress Centre, at Pavilhão de Civil.

Lisboa International Airport, 7 km from the city center and 3.5 km North of IST campus, has daily flights to and from major cities around the world. The Portuguese airline TAP Portugal as well as major international airlines flies to and from Lisboa. From the Lisbon Airport, which is located almost inside the city, is 3.5 km North of IST campus, you may use subway, bus or taxi to reach IST.

Subway The best option to get to IST is by subway/underground (Metropolitano de Lisboa). Just pick up the subway directly at the airport and leave on “Saldanha” station. Single ticket costs 1.45 €, and travel time is around 15 minutes. Single ticket is valid for 1 hour and can be used in both underground and buses. 24 h ticket costs 6 €.

Bus/Tram (Carris) Take Bus 744 or 783 at the side-walk near the Arrivals, and exit at “Saldanha”, 10 mins walk from IST. The ticket costs 1.80 €, if it is bought inside the bus. Bus 744 runs from 6 a.m. to 9 p.m., and Bus 783 runs from 6 a.m. to 0:15 a.m. (next day) and travel-time is around 20 minutes for both of the buses.

Taxi It will cost between 10 € and 12 € (depending on the hour, and if luggage boot is used). Travel time is around 10 minutes depending on the traffic. Hint: take the taxi at the Airport Departure level (instead of taking it at the Arrivals, where taxis line up for some time hoping for a long ride).

Hints getting here from other locations:

Google Maps can be used to choose the best option if you want to use public transportation (Bus and Subway) or just walk.

When buying Bus (except for onboard tickets) or Subway tickets for the first time, 0.50 € extra will be charged for the magnetic card (7 colinas / viva a viagem). This magnetic card is valid for 1 year, and it can be used with single tickets for a given transport, or it can be charged with money, called Zapping (with bonus when charged with larger sums) and used freely in both Subway and Bus (and on other local public transportation). Using Zapping, a single journey on Subway or Bus costs 1.25 €.

Title:

Regulatory Certification of Medical and Healthcare Devices Based on Regulatory Science for Global Compliance

Abstract:

Procedure of regulatory compliance testing healthcare devices as well as medical devices should be analytical and quicker for social service and business.

Regulatory science is an interdisciplinary subject between natural and social sciences because its aim is making a regulation for social wellness and services which can be acceptable under logical argument by all stakeholders while an approach of determining technical requirement for the regulation should be analytical using numerical evaluation of benefit versus risk of the employed technologies and the applied services in focused use cases such as regulatory compliance of medical and healthcare devices.

TECHNICAL SESSIONS

M1 - BAN TECHNOLOGY (PHY, MAC, PROTOCOLS)


Chair: Matti Hämäläinen (University of Oulu, Finland)

14h00 Performance Analysis of Cross-layer Approach About Error Control Scheme for WBANs

Kento Takabayashi (Yokohama National University, Japan); Hirokazu Tanaka (Hiroshima City University, Japan); Chika Sugimoto (Yokohama National University, Japan); Ryuji Kohno (Yokohama National University & University of Oulu, Japan).

Abstract In this paper, we analyze performance of our error control scheme in a cross-layer design for wireless body area networks (WBANs). As our previous work, we have proposed an optimal QoS control scheme that employs a multiplexing layer for priority scheduling and a decomposable error control coding scheme for WBANs. However, a cross-layer approach has not been considered yet. In this paper, we utilize a cross-layer approach at physical (PHY) and medium access control (MAC) layers and analyze performance of our proposed error control scheme and the standard scheme. Numerical results show our proposed scheme has better performances than the standard scheme. Additionally, the case utilizing a schedule access protocol has better performances than a random access protocol.

14h20 A Study for the Adaptive Error Correction Using QoS-HARQ Toward Dependable Implant Body Area Network

Satoshi Seimiya and Kento Takabayashi (Yokohama National University, Japan); Ryuji Kohno (Yokohama National University).

Abstract In this paper, we apply HARQ to a wireless feedback control system for realizing high dependable communication. We assume that a controller transmits packets of controlled variables through the propagation channel equivalent with the IEEE 802.15.6 CM2 using some punctured convolutional codes whose code rate is different each other. We propose QoS-HARQ which changes the code rate responding to the status of a rotary inverted pendulum before application for an implant medical actuator device. As a result, we confirm by computer simulations that our proposal can reduce the redundant bits in a packet while keeping the rotary inverted pendulum stable.

14h40 A MAC Protocol with Slot Prediction Algorithm for Wireless Body Area Network

Toshikuni Miyazaki (Yokohama National Universtiy, Japan); Tomohiro Fukuya (Yokohama National University, Japan); Ryuji Kohno (Yokohama National University & University of Oulu, Japan).

Abstract In this paper, we design a Medium Access Control (MAC) protocol for Wireless Body Area Network (WBAN) to allocate slot to packets of each medical and non-medical node. Although a hybrid MAC protocol is defined in IEEE 802.15.6 as the international standard of WBAN, the detail specification depends on the implementation. It is important to consider the Quality of Service (QoS) requirements of each node and packet in WBAN, because different sensor nodes generate time varying packets which generate depending on human behavior. Besides, permissible delay time of each medical and non-medical node is different. To improve both priority control for QoS and dependability, we propose a MAC protocol with slot prediction algorithm. Simulation results show that our protocol outperforms IEEE 802.15.6 in terms of transmission success rate and worst delay time.

15h00 Performance of the ETSI SmartBAN System in the Interfered IEEE 802.15.6 Channel

Harri Viittala (University of Oulu, Finland); Lorenzo Mucchi (University of Florence, Italy); Matti Hämäläinen (University of Oulu, Finland).

Abstract The ETSI TC SmartBAN defined system is designed for body area networks supporting both on-body links and links to implanted devices. The system operates at the 2.4 GHz ISM band, where there are also other wireless radio systems, such as Bluetooth and WiFi. The SmartBAN system simulation model has been created to Matlab and the system performance was studied in the IEEE 802.15.6 channel model 3 with a measurement based interference model. The interference model is based on the measurement campaigns carried out in the Oulu university hospital. By using these simulation models, comparative analysis between BCH encoding schemes (127,113) and (36,22) on the system performance was carried out. It is shown that a higher coding rate has better performance in the presence of interference but it needs a repetition method to gain an acceptable frame error rate.

15h20 Proposal Methods for Performance Analysis of WBANs Based on CSMA/CA

Do Thanh Quan (Yokohama National University, Japan & Le Quy Don Technical University, Vietnam); Pham Thanh Hiep (Le Quy Don Technical University, Vietnam); Takumi Kobayashi (Yokohama National University & Graduate School of Engineering, Japan); Kento Takabayashi (Yokohama National University, Japan); Ryuji Kohno (Yokohama National University & University of Oulu, Japan).

Abstract There have been burning issues on Wireless Body Area Networks (WBANs) in which performance analysis for media access layer (MAC) protocol is essential and has been discussed in many literatures. By using Markov chain model, saturation and non-saturation conditions, many works can calculate access probability and throughput of system. However, previous works usually assumed that channel is ideal and with both saturation and non-saturation conditions effect of remained packets, which were transmitted unsuccessfully due to collision or busy channel, was not considered adequately. The target of this paper is to evaluate system performance more accurately and flexibly, considering channel is non-ideal, taking into account the remained packets and using statistical mathematics instead of saturation and non-saturation condition and then to optimize parameters to achieve higher performance.

M2 - ANTENNAS AND RADIO PROPAGATION FOR WIRELESS BAN


Chairs: Jari Iinatti (University of Oulu, Finland), Custódio Peixeiro (IT/IST – University of Lisbon, Portugal)

16h00 3D Printed Antennas for Mm-wave Sensing Applications

Alexander Vorobyov (CSEM & Center Suisse d'Electronique et de Microtechnique SA, Switzerland); John Farserotu (CSEM, Switzerland); Jean-Dominique Decotignie (CSEM & EPFL, Switzerland).

Abstract This paper presents, three low cost 3D printed antenna concepts for integration with a miniature mm-wave platform. The proposed solutions are optimized to operate in mm-wave ISM band (122GHz-123GHz). Different, inexpensive, detachable antennas can be used with the same platform for various RF sensing applications such as food safety, health and industrial.

16h20 Formulas for Easy-To-Prepare Tailored Phantoms at 2.4 GHz ISM Band

Sergio Castelló-Palacios (Universitat Politècnica de València, Spain); Concepcion Garcia-Pardo (Universitat Politècnica de València & Institute of Telecommunications and Multimedia Applications (iTEAM), Spain); Alejandro Fornes-Leal (Institute of Telecommunications and Multimedia Applications, Spain); Narcis Cardona (The Polytechnic University of Valencia, Spain); Ana Valles-Lluch (Universitat Politècnica de València, Spain).

Abstract Emerging integration of communication networks into wearable or implantable body devices involves a challenge due to the transmitting medium, the body itself. This medium is heterogeneous and lossier than air, so devices that are supposed to work on it should be tested in tissue-equivalent materials. A number of materials with the electromagnetic response of body tissues have been proposed. Most of them are sucrose aqueous solutions that are supposed to simulate human’s muscle tissue mainly within medical frequency bands. However, these recipes are restricted to a single tissue and it is difficult to adapt them to fit the permittivity values of different body tissues. The significance of this study lies in the development of a mathematical relationship that models the dielectric properties of an aqueous solution according to the concentration of sugar and salt at 2.4 GHz, the frequency around which an Industrial, Scientific and Medical (ISM) band is placed. Thus, it becomes possible to create custom-made phantoms with simple and accessible ingredients that are easy to prepare in any laboratory.

16h40 Accurate Broadband Measurement of Electromagnetic Tissue Phantoms Using Open-Ended Coaxial Systems

Alejandro Fornes-Leal (Institute of Telecommunications and Multimedia Applications, Spain); Concepcion Garcia-Pardo (Universitat Politècnica de València & Institute of Telecommunications and Multimedia Applications (iTEAM), Spain); Sergio Castelló-Palacios and Ana Valles-Lluch (Universitat Politècnica de València, Spain); Narcis Cardona (The Polytechnic University of Valencia, Spain).

Abstract New technologies and devices for wireless communication networks are continually developed. In order to assess their performance, they have to be tested in realistic environments taking into account the influence of the body in wireless communications. Thus, the development of phantoms, which are synthetic materials that can emulate accurately the electromagnetic behaviour of different tissues, is mandatory. An accurate dielectric measurement of these phantoms requires using a measurement method with a low uncertainty. The open-ended coaxial technique is the most spread technique but its accuracy is strongly conditioned by the calibration procedure. A typical calibration is performed using an open circuit, a short circuit and water. However, this basic calibration is not the most accurate approach for measuring all kinds of materials. In this paper, an uncertainty analysis of the calibration process of open-ended coaxial characterization systems when a polar liquid is added to the typical calibration is provided. Measurements are performed on electromagnetically well-known liquids in the 0.5-8.5 GHz band. Results show that adding methanol improves the accuracy in the whole solution domain of the system, mainly when measuring phantoms that mimic high water content tissues, whereas ethanol is more suitable for measuring low water content tissue phantoms.

17h00 An Approach to Mean Path Loss Model Estimation for Off-Body Channels

Slawomir J. Ambroziak (Gdansk University of Technology, Poland); Kenan Turbic (INESC-ID / Instituto Superior Tecnico (IST), University of Lisbon, Portugal); Luis M. Correia (IST - University of Lisbon & INESC, Portugal).

Abstract This paper presents an approach to the estimation of mean path loss model parameters in off-body Body Area Networks channels. In this approach, the path loss exponent is constrained to a value obtained from line-of-sight (LoS) propagation in the co-polarised channel, considering a generalised static scenario. The proposed approach is compared to alternative ones, by evaluating the coefficient of determination for a set of measurements obtained in an indoor environment. Compared to a traditional approach, a relative improvement of up to 0.7 and typically above 0.4 is observed in the LoS case, while the goodness of fit is unchanged for the non-LoS case.

Abstract One of the main challenges for wireless body area networks (WBANs) is to evaluate realistic methods to generate channel models for new different purposes and various environments quickly and flexibly. Finite integration technique (FIT) has shown to be promising method for modeling channels characteristics in WBAN deployment scenarios. Applying simulation based channel modeling on the performance evaluations of the concrete use scenarios have not been presented yet in the literature. In this paper, FIT-based channel modeling is applied on the performance evaluation of IEEE 802.15.6 based energy detector (ED) receiver designed for monitoring the symptoms of Parkinson’s disease. First aim of this paper is to assess and compare the simulated channel impulse responses (CIRs) with the data from measurement campaign. . The second aim is to apply the simulated channel on the performance evaluations of the IEEE 802.15.6 based ED receivers. The obtained bit error rate (BER) performances are compared with BERs obtained using channel measurement data in the simulations. It is shown that performance obtained using FIT-based channel modeling corresponds to performance obtained using channel measurement data based channel modeling. The results of this paper further verify the statements that FIT is well applicable for WBAN channel modeling.

17h40 Path Loss Modeling for UWB Creeping Waves Around Human Body

Timo Kumpuniemi, Matti Hämäläinen, Juha-Pekka Mäkelä and Jari Iinatti (University of Oulu, Finland).

Abstract This article presents path loss models for creeping waves propagation around a human body at ultra-wideband frequency of 2–8 GHz. The results are based on measurements in an anechoic chamber using a vector network analyzer. Three antenna types are used: prototype dipole and double loop antennas together with the commercial Skycross antenna. The antennas are attached horizontally at the chest level and the waist level at in total 12 locations. Path loss values are defined from the first arriving paths of the channel impulse responses. Path loss models are developed for upper and lower horizontal body levels separately and for all available channels when also the cross channels between the levels are considered. The path loss exponents vary between 9.2-12.7 being clearly a higher result than previously reported. The double loop antenna has the lowest exponents and the commercial antenna the highest ones. No clear difference can be noted between the body and waist levels or when observing all channels. The scattering term of the path loss can be modeled with the generalized extreme value and generalized Pareto distributions.

Abstract Human body communication (HBC) is a wireless communication method that uses human body as part of the transmission medium. It uses electrodes instead of antennas to generate electric field around the human body. This electric filed forms capacitive couplings between transmitter, receiver, human body, and surrounding environment. Transmission from a transmitter on user’s wrist to an off-body receiver touched by the user was investigated. The human body wearing a transmitter was modeled as a signal source connected to the receiver input. The equivalent output impedance is composed of impedance of the human body and the capacitance of the capacitive coupling that is affected by the surrounding environment and the transmitter arrangement. Equivalent output impedance was estimated by maximizing the received signal power by adjusting input resistance of the receiver and by inserting inductance. Three types of transmitter electrodes and two types of receiver stands (wood and steel) were used to evaluate influences on the equivalent output impedance.

14h20 Determining the Transmission Efficiency for Human Body Communication Using a Multilayered Phantom

Dairoku Muramatsu (Tokyo University of Science, Japan); Naruto Arai (The University of Tokyo, Japan); Ken Sasaki (University of Tokyo, Japan).

Abstract Human body communication (HBC) is a wireless transmission method that utilizes the human body as part of the transmission medium. In HBC, a high-frequency signal is transmitted by a current flowing through the body surface and via the near-field electric field around it. Due to the lack of specific equipment and tools to measure HBC transmission characteristics, HBC systems are still in the development stage. In this study, a multilayered arm phantom and suitable measurement devices are proposed to measure the transmission efficiency between a 10-MHz transmitter worn on the wrist and a receiver in contact with the palm. Measurements with a real human subject were also performed. Additionally, numerical models for calculating the transmission efficiencies are introduced to validate the measurements. The transmission efficiencies obtained from the measurements using the phantom and from the simulation using the numerical model were in a reasonable agreement; however, the results of the measurements using the phantom and the subject differed, which we attributed to the effect of the body trunk.

14h40 Improving the Energy Efficiency for Biosensor Nodes in the WBSN Bottleneck Zone Based on a Random Linear Network Coding

Hisham Alshaheen and Haifa Takruri (University of Salford, United Kingdom).

Abstract The most important challenges in the design of a Wireless Body S ensor Network (WBS N) are the reduction of energy usage and the successful delivery of data. In general healthcare applications, the batteries of biosensor nodes cannot be easily recharged or replaced. Therefore energy consumption is a critical issue in WBS Ns, specifically, the nodes that are placed next to the sink node consume more energy, which limits the network lifetime because all biomedical packets are aggregated through these nodes forming a bottleneck zone. Therefore , this paper proposes a novel mathematical model for body area network (BAN) topology to explain the deployment and connection between biosensor nodes, simple relay nodes, network coding relay nodes and the sink node. The model uses Random Linear Network Coding (RLNC) to improve the energy efficiency for biosensor nodes in the WBS N bottleneck zone, combining saving energy with achieving the delivery of data if there is a failure in one of the links of the transmissions. A mathematical model for a WBS N was designed, and it was apparent that energy consumption is reduced and data delivery achieved with the proposed mechanism; this paper details the stages of the research work.

15h00 Energy Efficient UWB-WUR Dual-radio Solution for WBANs

Heikki Karvonen (University of Oulu, Centre for Wireless Communications, Finland); Juha Petäjäjärvi, Ville Niemelä, Matti Hämäläinen and Jari Iinatti (University of Oulu, Finland); Ryuji Kohno (Yokohama National University & University of Oulu, Japan).

Abstract A dual-radio solution for wireless body area networks (WBANs) is proposed in this paper. Solution is based on the usage of wake-up receiver (WUR) and impulse radio ultra wideband (IR-UWB) technique. In the proposition, the data to the hub is transmitted using IR-UWB and the control messages back to node using WUR. Energy efficiency model has been developed to compare proposed solution’s performance to a conventional duty-cycling based single radio solution. WUR design includes trade-offs between data rate, sensitivity and power consumption that are also explored in this work. Results show that the proposed solution can improve energy efficiency in WBANs which have asymmetric traffic between sensor nodes and hub in uplink and downlink direction.

15h20 Heart-rate Data Transmission Control for Vital Sensing from Densely-located Exercisers

Kazuki Okita, Hiroyuki Yomo and Takashi Kawabata (Kansai University, Japan).

Abstract In this paper, we investigate how to improve the reliability of heart–rate monitoring of a large number of people playing sports over a limited area of sports field. Densely–located nodes attached to exercisers transmit heart–rate data to a data collection node simultaneously, which negatively affects the reliability of data collection due to severe congestions caused by excessive traffic load. In order to solve this problem, we introduce a heart–rate data transmission control scheme where the sensed heart–rate is transmitted only when each node detects a larger variation than a fixed threshold. In order to analyze trade–off between the traffic suppression and increased sensing error through the introduced threshold, we first conduct experiments to obtain heart–rate variations during typical scenarios of exercises in a sports–day at schools in Japan. The obtained experimental data are then used to construct a model of heart–rate variations, which is then employed for computer simulations to evaluate the effectiveness of the introduced heart–rate transmission control. Our numerical results show that the heart–rate transmission control is effective, especially in a scenario where exercisers with different patterns of heart–rate variations coexist.

16h00 Parameter Optimization of Motion Artifact Canceling PPG-Based Heart Rate Sensor by Means of Cross Validation

Shinsuke Hara and Takunori Shimazaki (Osaka City University, Japan); Hiroyuki Okuhata (Synthesis Corporation, Japan); Hajime Nakamura (Aihara Second Hospital, Japan); Takashi Kawabata (Kansai University, Japan); Kai Cai and Tomohito Takubo (Osaka City University, Japan).

Abstract Photoplethysmography (PPG) is one of the simple and non-invasive heart rate (HR) sensing methods, but when applying it to a person during exercise, the output is contaminated with motion artifact (MA). Furthermore, when the pressure to stabilize the sensor on the skin surface is lower, extremely large values referred to as “outliers” are often observed in the sensed heart rate. To cancel the MA and reject the outliers, we have proposed an MA canceling PPG-based HR sensor, and have confirmed its effectivity for persons during vigorous exercises. However, the HR sensor contains several parameters to be adjusted to obtain better performance, although the number of experiments using subjects is limited due to its complexity. In this paper, we discuss a parameter optimization method for the MA canceling PPG-based HR sensor by means of cross validation. We apply the leave-one-out cross validation (LOOCV) to experimental data changing the values of the parameters, and then determine the ones which can minimize the root mean square error (RMSE). Finally, we show that the proposed HR sensor can achieve the RMSE of less than 7.1 beats per minute (bpm) for exercises of walking, running and jumping.

16h20 An Adaptive Scheme of Controlling Dosage and Dosing Interval in General Anesthesia by Model Predictive Control Using Anesthetic Depth Model

Yoshitomo Sakuma and Keiko Sameshima (Yokohama National University, Japan); Ryuji Kohno (Yokohama National University & University of Oulu, Japan).

Abstract In this paper, we proposed a dosage control system for total intravenous anesthesia (TIVA) in order to help anesthesiologists and enable to manage multiple operation remotely by one anesthesiologist. In the general anesthesia, constraints of a drug dosage and the value of biological information indicating anesthetic depth must be taken into account. Also, introduction time of anesthesia and time to awake after surgery is required to be short with satisfying above restrictions. Furthermore, if surgery periods are extended, anesthetic effect should be maintained during surgery. From this point of view, we proposed an adaptive scheme of controlling the dosage and the dosing interval by model predictive control in order to satisfy such complicated requirements.

16h40 Dynamic Stopping Using eSVM Scores Analysis for Event-Related Potential Brain-Computer Interfaces

Vo Anh Kha and Diep N. Nguyen (University of Technology Sydney, Australia); Ha H Kha (Ho Chi Minh City University of Technology, Vietnam); Eryk Dutkiewicz (University of Technology Sydney, Australia).

Abstract In brain-computer interface (BCI) research, there must be a trade-off between accuracy and speed of the BCI system, especially those based on event-related potentials (ERPs). This paper proposes a novel method which can significantly increase the spelling bit rate while also maintaining the desired accuracy. We provide an adaptive real-time stopping method based on the scores of ensemble support vector machine classifiers. We apply a criteria assessment process on the classifiers’ scores to dynamically stop the ERP-evoked paradigms at any flashing sequence. Our experiments were conducted on three different P300-Speller data sets (BCI Competition II, BCI Competition III and Akimpech). Our proposed framework significantly outperformed the related state-of-the-art studies in terms of character output accuracy and elicitation bit rate rise between static and dynamic stopping schemes. We improve the average bit rate by over 80% while perfectly maintaining the best original static accuracy of over 96%.

Abstract Harmonic Motion Microwave Doppler Imaging method, which was proposed as an alternative method for breast tumor detection, is a combination of microwave radar and focused ultrasound techniques yielding data depending on electrical and mechanical properties of the tissue. In this study, Harmonic Motion Microwave Doppler Imaging data from a small tumor inside homogeneous fat is analyzed as a function of tumor location on three orthogonal planes using Finite Difference Time Domain simulations. The results show that the resolution on the order of millimeters is achievable with this method.

17h20 Integrated Electromyography Visualization with Multi Temporal Resolution

Pedro Cardoso (Instituto Superior de Engenharia de Lisboa, Portugal); Nuno Datia (ISEL, Portugal); Matilde Pato (Instituto Superior de Engenharia de Lisboa & ISEL, Portugal)

Abstract For the analysis and comparison of electromyography (EMG) signals from different patients, standardization techniques are used to calculate the integrated EMG signal (iEMG), useful to evaluate the level of activity of different muscles. The iEMG corresponds to the area under the rectified curve (AUC). Currently, monitoring and follow-up of these patients is done in regular health exams where the evolution of patients is assessed. The monitoring includes performing multiple clinical trials. The goal of this paper is to help medical staff assessing the evolution of amyotrophic lateral sclerosis (ALS) disease by analyzing the collected data. The signal, described by the electromyogram, can be measured applying conductive elements or electrodes to the skin surface. The electrical activity of skeletal muscles is continuously measured for at least 24 hours. In this work we used an appropriate data model to store data generated by EMGs, optimized for analytical processing. We implemented a Web API in order to provide access to the model data in an agnostic way, both to database management systems and data consumers. We implemented a web application to visualize data through the use of several interactive charts. Usability testing helped to validate the solution, confirming the ease of use of the web application and the fulfilment of all the proposed goals. The telemonitoring ALS patients doesn’t change mortality but reduces the need for hospitalization and costs for patient.
