Slicer-IGT/GPU-IGT/112707

1. 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 accelerated Slicer for 4D IGT.

1. Nicholas update on his CUDA project

• Rigid and non-rigid registration using CUDA using Nvidia 8800 GTX (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

1. 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

1. Extension to ITK

• CMake turn on/off #DEFINE
• VTK VolumePro as part of volume redering
• ITK parallelized process
• [Action items, Nichoals] Mid-term goal for Nicholas is to port his rigid and non-rigid regstration to ITK
• [Action items, Nicholas] Contact Utah team hear how exactly they implement their ITK.
• [Actoinj items, Nicholas] sending volume rendering code by Dec. 6th.

1. Volume rendering

• CUDA accelerated volume rendering
• x15 - 20 improvement
• comparison to other people's CG-based volume rendering media:SIGGRAPH-GPU.pdf
• [Action items, Benjamin] port CUDA-based volume rendering to vtk volume rendering classes, and then to Slicer
• [Action items, Benjamin] succeed Nicholas' itk-cuda-rigid non-rigid regstration and port them to Slicer in the context of MRg cardiac ablation

1. Timeline

• NH will write paper on IV-CUDA rendering for Journal
• Hata suggested publication of ITK-CUDA registration in Insight Journal (Feb)
• Benjamin will have short summery as of March 15 for MICCAI.
• Benjamin will finish his project by May 15th.

1. Communication

Bi-weekly t-con to update each other week. Next one is Dec 11, 2007 at 9am.
