AUTOMATIC PATIENT TABLE

摘要

AUTOMATIC PATIENT TABLE A versatile patient table system for transverse axial scanners employs front and rear tables with a spanning patient pallet for abdominal scans. A motorized conveyer belt on the front table increments the axial position of the patient. For brain scans the rear table and patient pallet are replaced by a head restraint assembly with a hinged headrest, cheek pad restraint members and a body pad which rests on the conveyer belt on the front table. In the automatic mode of operation, the belt moves either the body pad or the patient pallet out from the scanner in controlled increments triggered by the image processor. The hinged metal seam of the belt is used for indexing the extreme outward and inward positions.
