Evaluation of a method for projection-based tissue-activity estimation within small volumes-of-interest

A new method of compensating for tissue-fraction and count-spillover effects, which requires tissue segmentation only within a small volume surrounding the primary lesion of interest, was evaluated for SPECT imaging. Tissue-activity concentration estimates are obtained by fitting the measured projec...
