ABSTRACT:
The system of the present invention uses x-rays having a narrow fan beam to scan patients for bone density and soft tissue body composition measurement and imaging. In addition to single pass scanning of body parts such as the spine, hip and forearm, a method for multiple pass whole body scanning is provided. The system includes a movable scan table configured to support a patient and a C-arm associated with the table. The C-arm is configured to support an x-ray source in opposite to an x-ray detector at opposite sides of the patient. A scanning mechanism is provided to move the scan table and C-arm to scan the patient with overlapping adjacent x-ray fan beams in successive scan passes along the length of the patient. A scan pass combination scheme that blends areas of overlap is employed to compensate errors related to height dependency. The blending is performed according to the height of the part of patient scanned in the overlap and the distance from the edge of the scan pass.
