MIAL

Analysis and Visualization of Time Varying Medical Image Data

PhD Student: Ahmed Saad
Alumni: Zhe Fang
Principle Investigator: Torsten Möller
MSc Student: Benjamin Smith
Principle Investigator: Ghassan Hamarneh

We are developing algorithms for visual exploration and quantitative analysis of spatio temporal medical imaging data such as dynamic SPECT and dynamic PET.

This project is in collaboration with Dr. Anna Celler, Vancouver General Hospital, and Dr. Philip Cohen, Lions Gate Hospital.
