Abstract: A SPECT diagnostic method of performing myocardial perfusion imaging on a patient, the method including (A) commencing a mycocardial perfusion diagnostic scan; (B) during the scan, determining the photon count rate; (C) using the photon count rate and a predetermined total photon count target, determining a scan duration time; (D) terminating the diagnostic scan when the scan duration time elapses.

Abstract: A photon detector for use in imaging, comprising a detector surface for detecting photons incident on the detector surface, the detector surface comprising at least one non-flat feature configured such that, during imaging, at least a portion of the photons are blocked from incidence upon at least a portion of the detector surface.

Abstract: A SPECT diagnostic method of performing myocardial perfusion imaging on a patient, the method comprising the steps of: administering a rest radiotracer to the patient while the patient is at rest; scanning the heart of the patient, with the patient positioned at a scanning position, to obtain a rest perfusion image; administering a stressing agent to the patient to place the patient's heart under stress; administering a stress radiotracer while the heart of the patient is under stress; scanning the heart to obtain a stress perfusion image; maintaining the patient at the scanning position from the commencement of the rest perfusion image through the completion of the stress perfusion image.

Abstract: A SPECT diagnostic method of performing myocardial perfusion imaging on a patient, consisting of (A) administering a rest radiotracer to the patient while the patient is at rest; then (B) when the rest radiotracer is fixed in a heart of the patient, scanning the heart to obtain rest heart pumping ability information; (C) scanning the heart of the patient to obtain a rest perfusion image; (D) administering a stressing agent to the patient to place the patient's heart under stress; (E) scanning the heart of the patient to obtain stress heart pumping ability information; then (F) administering a stress radiotracer while the heart of the patient is under stress; then (G) when the stress radiotracer is fixed in the heart, scanning the heart to obtain a stress perfusion image.
