Towards accurate 177Lu SPECT activity quantification and standardization using lesion-to-background voxel ratio

Conventional calibration of the gamma camera consists of the calculation of calibration factors (CFs) (ratio of counts/cc and true concentration activity) as the function of the volume of interest (VOI). Howev...
