Ga-67 Tumor Detection using Penalized-EM with Nonanatomical Regularizers
Abstract
Results from localization ROC (LROC) observer studies evaluating a penalized-likelihood SPECT reconstruction algorithm are presented. Both human and numerical observers were employed for the task of Ga-67 tumor detection in simulated chest images. Projection data from a mathematical phantom were generated with the SIMIND Monte Carlo program. Reconstructions using De Pierro's modified-EM algorithm [1] with the 3D quadratic and Huber penalty …
