摘要： A method, process and apparatus for improved nuclear imaging. Specifically, the disclosure relates to improving detection of true coincidence events and differentiating them from events detected from scattered and random gamma photons. Embodiments comprise receiving electromagnetic radiation at a plurality of photo detectors that was generated by a scintillating crystal impacted by a gamma photon. Embodiments further comprise processing data received at a subset of the plurality of photo detectors that are closer to a scintillating crystal, thereby improving a timing coincidence window for detecting a coincidence event.

摘要： A patient bed for use with at least one imaging device in which a plurality of scans to be correlated are performed, as well as in a continuous motion scanner used to compile whole-body scans. The patient bed includes a horizontal rail base and a movable patient surface. Electronic controllers are provided for controlling the horizontal and vertical positioning of the patient surface. The horizontal rail base is secured to the support proximate the scanner. A linear motor is used to generate horizontal motion of the patient bed. The linear motor is controlled using a motion controller in communication with a computer associated with the imaging device. A pedestal is provided for mounting a vertical carriage assembly. A vertical track is carried by the pedestal for controlling vertical travel of the patient bed. A motor is provided for controlling vertical motion. A pallet support member is cantilevered from the vertical carriage assembly for carrying a pallet.
