Virtual Detector FDK for twin robotic CT reconstruction
Abstract
The presented Virtual Detector FDK combines a virtual detector and a standard FDK implementation to cover trajectories where the source is moved on an ideal circle but the detector has to deviate from its ideal trajectory. This algorithm enables efficient analytic and region-of-interest reconstructions instead of iterative reconstructions in some use-cases of twin robotic CT systems. The presented work implements and evaluates the approach for simulated non-truncated and measured non-truncated projections.
