Abstract
This invention features an integrated single photon emission computed tomography (SPECT)/transmission computed tomography (TCT) system for cardiac imaging including an open arc-shaped frame. A collimator system is shaped to approximately match the thoracic contour of patients having different sizes and weights and shaped to surround and position the collimator closely proximate a heart of a patient of said patients encompassed by at least one predetermined image volume for optimizing collimation of radiation photons emitted from the heart. An arc-shaped detector system is coupled to the collimator subsystem having a shape closely matching the shape of the collimator subsystem for detecting collimated radiation photons from the collimator subsystem and generating output electrical signals. A patient positioning subsystem positions a patient to a predetermined central longitudinal axis of the three-dimensional imaging volume and for intermittently and incrementally rotating the patient about the predetermined central longitudinal axis for generating a plurality of TCT images.
