This study investigates the fidelity of approximations involved in the FDK algorithm. Test data is obtained by the cone-beam X-ray scanner developed at the Institute of Cancer Research (Surrey, England). The er
A collapsed cone convolution algorithm was applied to a treatment planning system for the calculation of dose distributions. The distribution of beam fluences was determined using a three-source model by considering the source strengths of the primary beam, the beam scattered from the primary ...
owing to its mechanical simplicity, which only requires a single degree of freedom. However, this trajectory does not fulfill the well-known Tuy-Smith sufficiency condition, which leads to the formation of cone beam artifacts and several alternative shapes, such as the helix or the circle-...

Based on our recently derived exact fan-beam LT formula, here we propose a practical cone-beam LT algorithm for LT reconstruction from local data collected along an arbitrary smooth 3D curve. A key step in our algorithm is to determine an appropriate vector perpendicular to the line connecting ...
Cone beam computed tomography (CBCT) has become the standard of reference in dental imaging. The distribution of CBCT devices is increasingly wide, and the number of required examinations is constantly growing. In this setting, it is now essential that medical and technical staff receive specific ...
