<p>A single photon emission computed tomography system produces multiple tomographic images of the type representing a three-dimensional distribution of a photon-emitting radioisotope. The system has a base including a patient support for supporting a human patient such that a portion of the patient's torso is located in a field of view. The patient's torso extends generally vertically such that the patient's head is substantially higher than the patient's hips. A longitudinal axis is defined through the field of view, with the longitudinal axis being generally vertical. A detector assembly is adjacent to the field of view and includes a photon-responsive detector operable to detect if a photon strikes the detector. The detector assembly is operable to scan for photons emitted from the portion of the patient's torso located in the field of view. The patient remains stationary during the scan.</p> |
