Effect of scatter correction when comparing attenuation maps: Application to brain PET/MR

Name: Work Video:
Duration: 3 min 30 s
Description: In PET imaging, attenuation and scatter corrections are an essential requirement to accurately quantify the radionuclide uptake. In the context of PET/MR scanners, obtaining the attenuation information can be challenging. Various authors have quantified the effect of an imprecise attenuation map on the reconstructed PET image but its influence on scatter correction has usually been ignored.
