Abstract
A new reconstruction strategy is proposed for 3D images acquired with rotating PET scanners. This method is based on the decomposition of the system response matrix (SRM) into a projection and a rotation components that are inverted independently. We present the rationale of the new reconstruction procedure as well as some examples to compare with analytical 3D reconstruction (3DRP) and 3D statistical reconstruction (3D-OSEM)
