<p><b>New page</b></p><div># Introduction of members of this project<br />
* Nicholas: student from Tokyo <br />
* 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 accelerated Slicer for 4D IGT. <br />
<br />
<br />
# Nicholas update on his CUDA project<br />
* Rigid and non-rigid registration using CUDA using Nvidia 8800 GTX (350GFlps) compatible with CUDA platform.<br />
* Rigid registration (Japanese cas paper) <br />
[[Image:RigidReg.jpg]] <br />
<br />
Rigid registration using affine transformation, MI similarity measure, and Powell optimization method impletented on CUDA platform. GPU-acceleration was performed on affine transformation and MI similarity measure. Performance boost of around x12 was achieved.<br />
* Non-rigid registration (also Japanese cas paper)<br />
[[Image:NonrigidReg.jpg]] <br />
<br />
Non-rigid registration using Rueckert's B-spline algorithm. Performance boost of around x10-x20 was achieved.<br />
<br />
#Tool kit used<br />
*CUDA calculator<br />
*8800GTX, 8800GTS, Quadro FX5600, Tesla C870 is CUDA 1.0 compatible<br />
*8600GTS, 8800GT is CUDA 1.1 compatible which comes with Atomic function to control cuncurrent access to memoery from multiple thread<br />
<br />
# Extension to ITK<br />
* CMake turn on/off #DEFINE<br />
* VTK VolumePro as part of volume redering<br />
* ITK parallelized process <br />
* [Action items, Nichoals] Mid-term goal for Nicholas is to port his rigid and non-rigid regstration to ITK<br />
* [Action items, Nicholas] Contact Utah team hear how exactly they implement their ITK.<br />
* [Action items, Nicholas] sending volume rendering code by Dec. 6th.<br />
<br />
# Volume rendering<br />
* CUDA accelerated volume rendering<br />
* x15 - 20 improvement<br />
* comparison to other people's CG-based volume rendering [[media:SIGGRAPH-GPU.pdf]]<br />
* [Action items, Benjamin] port CUDA-based volume rendering to vtk volume rendering classes, and then to Slicer<br />
* [Action items, Benjamin] succeed Nicholas' itk-cuda-rigid non-rigid regstration and port them to Slicer in the context of MRg cardiac ablation<br />
<br />
# Timeline<br />
* NH will write paper on IV-CUDA rendering for Journal<br />
* Hata suggested publication of ITK-CUDA registration in Insight Journal (Feb)<br />
* Benjamin will have short summery as of March 15 for MICCAI.<br />
* Benjamin will finish his project by May 15th.<br />
* Benjamin <br />
