Abstract
The invention relates to a system and a method for assisting in attenuation correction of gated PET data of a moving object (). In the system, an evaluation unit () is configured to (i) receive a CT image of the object () and to segment the CT image into a plurality of CT sub-images, each CT sub-image correspond to an axial segment of an imaged volume, (ii) to determine for each CT sub-image a gate including PET data having a greatest correspondence with the CT sub-image, (iii) to construct, for each CT sub-image, a PET sub-image from the PET data included in the gate determined for the CT sub-image, the PET sub-image substantially corresponding to the same axial segment of the imaged volume as the CT sub-image, and (iv) to combine the PET sub-images to form a PET reference image of the object ().
