This paper shows the potential of segmenting the liver from CT, CBCT, and CBCT TST, learning from the available limited training data, which can possibly be used in the future for the visualisation and evaluation of the perfusion maps for the treatment evaluation of liver diseases.

Cutting Voxel Projector a New Approach to Construct 3D Cone Beam CT Operator

1 code implementation • 19 Oct 2021 • Vojtěch Kulvait, Georg Rose

We have implemented this cutting voxel projector and a less accurate, speed-optimized version of it together with two established projectors, a ray tracing projector based on Siddon's algorithm and a TT footprint projector.
