ABSTRACT:
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.
