# Introduction of members of this project
* Nicholas: student from Tokyo 
* Benjamin: student from ETH, be at SPL for 6 mo. till May 31, 2007. Experience in golfing simulator, histoscopy simulator, open-source game software. His project here is GPU accerelated Slicer for 4D IGT. 


# Nicholas update on his CUDA project
* Rigid and non-rigid registration using CUDA using Nvidia 8800 GTK (350GFlps) compatible with CUDA platform.
* Rigid registration (Japanese cas paper) *******to be filled by Nicholas ****** x12
* Non-rigid registration based on (Rueckert et al.). achieved x10-x20 

#Tool kit used
*CUDA calculator
*8800GTX is CUDA 1.0 compatible
* XXXX is CUDA 1.1 compatible which comes with Atomic function to control cuncurrent access to memoery from multiple thread

# Extension to ITK
* CMake turn on/off #DEFINE
* VTK VolumePro as part of volume redering
* ITK parallelized process 
* [Action items] Mid-term goal for Nicholas is to port his rigid and non-rigid regstration to ITK
* [Action items] Contact Utah team hear how exactly they implement their ITK.
