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 ...
