1. 1. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Albin Lindvall; [2023]
   Keywords : Medicine and Health Sciences;

   Abstract : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.
