In order to quantitatively measure the distribution of the radiotracer in vivo accurately, corrections for randoms, scatter and attenuation need to be applied. Upon data collection all coincidences are stored in list mode or sinograms and represent the projection data. The projection data are then reconstructed into an image representing the activity radiotracer distribution in the patient. Corrections for randoms, scatter and attenuation are applied during this process. Various different reconstruction methods are available such as filtered back projection and[…]
