An Investigation of Projection Sampling for Ga-67 Tumor Detection
Abstract
Psychophysical studies were used to investigate the effect of number of projection angles $\Phi$ on images reconstructed from simultaneous emission-transmission scans of fixed duration. The specific task was detection and localization of Ga-67 tumors in simulated images of the thorax, and a Tc-99m transmission source was modeled in the data acquisition. Reconstructions with the rescaled block-iterative (RBI) expectation-maximization algorithm …
