I am keen on generating a Digitally reconstructed radiograph (DRR) from 3D-CT image volume which is based on the volume rendering concept. Ray casting tries to find the intersections of a ray with all objects or voxels in the volume. Interpolation can be nearest-neighbor, tri-linear, etc.
Can you point me a good source for getting code for DRR generation. I know some of the CT systems like GE's Advanced workstation (AW) can create DRR. However, I have CT images collected from another source and do not know how to create a DRR. Any direction into a software or even a piece of code would be helpful.

Thanks,
Ganesh
