Fully 3-D List-Mode OSEM Accelerated by Graphics Processing Units

Abstract

Advanced list-mode image reconstruction algorithms such as fully 3D list-mode ordered-subset expectation maximization (OSEM) are needed to exploit the potential performance of high-resolution PET systems with depth-of-interaction capabilities. However, such algorithms are computationally intensive. With the aim to accelerate list-mode 3D-OSEM, we… (More)
