Fast, Accurate and Shift-Varying Line Projections for Iterative Reconstruction Using the GPU
List-mode processing provides an efficient way to deal with sparse projections in iterative image reconstruction for emission tomography. An issue often reported is the tremendous amount of computation required by such algorithm. Each recorded event requires several back- and forward line projection...
