Picture 44. Remote DICOM archive settings.

To check remote DICOM archive - requires LOCAL VS AET TITLE to be registered on remote DICOM archive. Press

button to send DICOM C-ECHO and verify basic connectivity by DICOM protocol.


WORKLIST – setup DICOM modality worklist server connection. This enables to search scheduled DICOM modality

worklist (scheduled patient procedures).

• AET TITLE – max 16 Latin1 characters. Requires to ask your administrator for this entity title to identify DICOM

modality worklist server.

• HOST OR IP ADDRESS – worklist server host or IP address. It is recommended to set IP address for faster network

lookup.

• PORT – max 65535 number. DICOM protocol common use is 104 or 11112 ports. Recommended to consult

administrator.



• CHARSET – setup encoding for worklist results. Result comes in DICOM standard and most results do not define

encoding – need to be set and tested manually.

• WORKLIST WILDCARD – add wild card symbol “*” on search parameters. Some worklist servers do not support

this for example on patient ID or accession number and requires to search exact patient ID or accession number.

Recommended to consult with administrator (typically this information can be found in worklist server or DICOM

archive conformance statement document).

Picture 45. Worklist settings.

To check worklist server - requires LOCAL VS AET TITLE to be registered on worklist server. Press button to

7.2 Recording settings

Recording settings let you manage video input sources. Allows to define multiple input source configurations – profiles.

Picture 46. Recording settings.

Activate source profile - display video input source streaming window in application include on startup.

Update or change source profile settings.

Delete source profile. If source is active – requires to stop source.

Reload all active sources.

Add new source profile.

Can copy full stream address.

Download VLC media player format playlist file, that contains the same stream address.

Do not enable the same video input source from multiple profiles. For e.g. added camera to profile A and

the same camera to profile B and enabled both of them, to be active in VS application. In this situation,

just profile A will start and profile B will fail, because input signal will be taken.

There are possibility to play A and B profiles, but card must allow this (play input signal via windows

direct show and other via capture card interface – if this exist). This possibility does not make any seance

to have 2 the same signals recording and it can cause unstable input stream recording process.



Input source profile is identified by UNIQUE PROFILE NAME input

text. If user enters the same profile name – will change existing input

source profile data. In order to create new profile – enter different

UNIQUE PROFILE NAME input text.

DEVICES – input source like camera or video capture board. Select

one of founded device.

If cannot see any devices or some is missing – please

check connection cables to the device. If problem

persist - check Windows OS device list, if all drivers

installed properly.

DIRECTSHOW - enables to get input device signal through Windows

OS DirectShow API.

VS application is using YUAN video capture board SDK API and can

access capture board signal with lowest latency compared to

DirectShow.

ENABLE RECORDING KEYS – enable to control profile source

recording with pedals (see 7.1.1. General settings).

VIDEO INPUTS – define what cable input type video signal.

AUTO – try find capture board signal, but recommended to consult

with VS PC administrator about capture board input type and select

correct one.

AUDIO INPUT – defines, how to get audio signal. This option

depends on device input or device itself. If using simple USB camera

with microphone array - should work with EMBEDED option. If

using video input HDMI (audio should come with the same cable) -

should work with EMBEDED option.

With other audio capture boards or other audio input device signals -

requires to see and setup WINDOWS OS audio devices or redirect

audio signal to capture board. This situation is a little bit tricky and

requires testing to configure input signal environment.

QUALITY PROFILES – defines video and image attributes: video

size, frame rate, audio channels, compression and others.

One of important attribute is DICOM transfer syntax:

1.2.840.10008.1.2.4.100 and 1.2.840.10008.1.2.4.101 - MPEG2

video for older medical devices.

1.2.840.10008.1.2.4.102 and 1.2.840.10008.1.2.4.103 – MPEG-4

video for most of devices.

It is important to select DICOM transfer syntax according hospital

DICOM archive (PACS). Some archives are very old and do not

support some of transfer syntax. Recommend to consult with DICOM

archive administrator (see DICOM archive conformance statement

document).

VS software will try to scale medical device output signal to match

settings. Recommended to select close enough or the same resolution

for medical device output signal to ensure best quality.



ENCODER – define PC resources during video compression.

SOFTWARE – default option to use CPU.

INTEL_MEDIA_SDK – to use Intel integrated GPU. This requires

to install Intel media SDK from https://software.intel.com/en-

us/media-sdk/choose-download/client .

RECORD INTERVAL – defines one video size in seconds. Default

value is 1800s = 30min for average quality.

Requires a little bit testing, because it depends on video quality. VS

application built for 32bit architecture system to run on most of

Windows OS and limitation is 2GB of video size. Try record small

chunk of video and calculate max size (more dynamic video – more

frames will be added).

RECORD QUALITY – try adjust video quality from 1-5 (low to

high). Some capture devices have different quality capabilities and

this calculation will be different. Sometimes it depends on OS

compatibility with capture device.

DISPLAY CALIBRATION – enchant video view.

STREM ENABLED – enable input source signal to stream by RTSP

protocol via network.

If profile has DIRECTSHOW enabled – all STREAM

options will not be possible.

STREAM PROFILE – select one of desired video compression and
