Imaging for Physicists

Image Formation

(1) Emission scan (2) Normalization scans (one per plane in 2D) to correct for differential detector efficiencies and geometric effects related to the detector ring (3) Set of sinograms of attenuation correction factors to correct of photon attenuation (self- absorption or scattering) by the object
