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 preseA 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)[+][-]
