Title: Rotate-and-Slant Projector for Fast LOR-Based Fully-3D Iterative PET Reconstruction

Summary:

One of the greatest challenges facing iterative fully-3D reconstruction is the issue of long reconstruction times. We have developed a rotate-and-slant projector which takes advantage of the symmetries in the geometry to compute projections to multiple oblique sinograms in a computationally efficient manner. In this seminar, the rotate-and-slant projector will be described, and a number of numerical issues will be discussed for efficiently implementing the projector in C. Methods for modeling geometric, multiplicative, and additive ECT effects will also be discussed. Hope to see your there.
