== Progress ==
=== Assignment 1 ===
=====Background=====
In assignment 1 we identified the 'RCTAlgorithmBackprojection' function located in the dll/shared library was taking up virtually 100% of the execution time. Our goal for this assignment was to off-load that logic to the GPU using cuda api, leaving everything else intact.
=====SummaryProcess=====
The work we did can be separated in to three basic steps:
#Compile base software from source (RabbitCTRunner.exe and dll)
=====Graph=====
This graph represents for only 128 volume size.
[[Image:sonicgraph1.png|left|frame|widthpx| ]]=====Summary=====      As you can see, using cuda has improved the performance by ~99.85%, we went from over 5 minutes to under a second. However, this code still needs to be optimized and run on bigger volume sizes. This will be our next goal.
=== Assignment 3 ===
