Hello, I'm struggling to reconstruct properly a synthetic projection images sequence using RTK. The sequence was generated using gVirtualXRay (https://gvirtualxray.fpvidal.net/) and a dragon 3D model, and represents a full 360 degrees CBCT tomographic sequence, with a 500mm SID and 1000mm SDD, 0.5mm pixel size with a 640x480 image resolution, and without any offsets (perfect circular geometry). I tried reconstructions with the simplest FDK and SART implementations, inspired by RTK provided code examples, using rtk::ProjectionsReader to read the images and rtk::ThreeDCircularProjectionGeometry to read the geometry, but the results are not good, and I don't really know if the problem comes from the data or from my reconstruction implementation.
The images data, as well as the xml geometry I generated, are available for download at this link: https://filesender.renater.fr/?s=download&token=bc8f87b4-989c-46d7-8c4b-dac39a4df0e1 Could you help me pinpoint the origin of my problem? Does it come from the data itself?
