TOF PET 3D reconstruction adds another layer of complexity. Thus it becomes a challenge to find the most efficient method to optimize the reconstruction without compromising image quality. In this study, mCT PET scanner data is used for image reconst

Continuous Bed Motion (CBM) acquisition has a number of advantages over the traditional Step-and-Shoot (SS) mode, including: Uniform axial signal-to-noise ratio, improved resolution due to subsampling in the axial direction, and reduction of noise du

Animal PET scanners are typically designed to image small subjects, such as mice and rats. This makes the tomographic reconstruction sensitive to parallax affects, and makes resolution recovery essential for good quality images. In this study, data w
