IntroductionThe simultaneous use of images obtained from different sources (modality)

造影源優點缺點一般用途及特別用途

CT X 射線快速掃描骨頭及軟骨

高成本應用範圍有限游離輻射

血塊骨折手術房 / 急診室腦瘤

MRI 磁場軟組織骨組織內部非侵入性

高成本無法獲得骨骼影像耗時

腦部疾病 / 腫瘤腦下垂體瘤多發性硬化症 / 髓鞘值惡化

PET 放射性同位素

評估代謝功能即時造影使用多種放射性追蹤劑

高成本研究導向空間資訊少複雜需要迴旋加速器

癲癇 / 抽搐癌症柏金森氏症艾滋海默氏症腦部功能定位研究

Requirement

RegistrationTo represent the same object of interest to a common coordinate system

Match two of more image, or volumesFrom different times, sensors, scanners or viewpoints

Reference imageMap pixels from one image

Test imageTo pixels in another image

Requirement

Interaction toolTo provide ways to manipulate the data

Extract measurements and functional information

Allow different types of visualization

Navigation inside the structures

The computational cost is very highSeveral acceleration techniques have been developed

15


One of the largest challenges??Development of strategies

Requirements for the development of a new system

Have multimodal visualization features

Use the optimize algorithms

Reuse software

Easy to use

16


Model-View-Controller (MVC)Model

Encapsulates core data and functionality

ViewDisplay information to the user

ControllerReceive input

– Mouse movement, activation of mouse buttons, or keyboard input

Conclusions

Find suitable strategies to integrate multiple data sets

Design user-friendly interface

Integrate all techniques
