Driving problems:
Kilian Pohl, BWH-MIT (Inter-subject mapping)
Steve Pieper, Isomics (fMRI to high-res MRI)
Sandy Wells, MIT (EPI/MRI)
Sylvain Bouix, BWH (DTI component registration)
Algorithms: Identify ITK registration methods, specify component tests, collect test data. Challenge: Test speed and maintain accuracy
Software: Identify/develop cross-platform timing system, implement component tests, centralize data and results, identify bottlenecks, parallelize and re-test. Challenge: Cross-platform multi-threaded timing
Driving Problem: Validation of results.
Expected Date for Insight Journal Publication: August, 2007
Accomplished by end of Programming Week
Driving problem will be Killian Pohl’s head MRI/MRI registration task
B-Spline registration is the technology
Speeding image resample will be initial component test
Data has been centralized on MIDAS
Intel dual-core platform chosen for optimization since an open-source, cross-platform, profiling tool with multi-core support could not be found
Secondary problems for DTI and fMRI also identified, and their data has been centralized
Optimized code will be delivered using the Slicer B-Spline Module
