Optimization of derivative kernels for exact cone-beam ROI reconstruction in spiral computed tomography

A recent comparison study showed that exact, FBP-based solutions of the long object problem are numerically stable and that their image quality is mostly affected by filter design. In this paper the impact of the kernel design on image quality is demonstrated systematically in the case of the local...
