Abstract
A positron emission tomography (PET) data processing method comprises obtaining PET data from a PET detector, wherein the PET detector comprises an array of detector elements, and wherein the PET data is representative of a PET measurement of at least part of a subject. The method comprises identifying in the PET data a plurality of paired events, wherein each paired event comprises a first photon event in a first region of the PET detector and a second photon event in a second region of the PET detector. The first photon event comprises an energy deposition in a first detector element of the array or in a first detection region of the first detector element due to a scattering of a first photon at a first azimuthal scattering angle and an associated energy deposition by the scattered first photon in a second detector element of the array or in a second detection region of the first detector element or of the second detector element. The second photon event comprises an energy deposition in a third detector element of the array or in a third detection region of the third detector element due to a scattering of a second photon at a second azimuthal scattering angle and an associated…
