Abstract:
1. A single photon emission computed tomography (SPECT) system for cardiac imaging comprising: a stationary open arc-shaped frame; a stationary open arc-shaped collimator subsystem for optimizing collimation of radiation photons emitted from the heart, the collimator subsystem configured to: approximately match the shape of the thoracic contour of patients having different sizes and weights, locate the collimator subsystem closely proximate a heart of a patient and define a plurality of predetermined image volumes each having a central longitudinal axis, each of the plurality of predetermined imaging volumes configured to encompass the heart of patients of different sizes and weights; a stationary open arc-shaped detector subsystem proximate the collimator subsystem and having a shape generally matching the shape of the collimator subsystem configured to detect collimated radiation photons from the collimator subsystem and generating output electrical signals for the generation of one or more SPECT images and; a computer subsystem configured to receive the digitized output electrical signals from the detector subsystem and generate a plurality of SPECT images of the heart.
