Abstract
A CT imaging system comprising a frame having a center opening and a uni-body construction; a CT imaging unit mounted to the frame and comprising: a rotatable drum assembly rotatably mounted to the frame, concentric with the center opening, wherein at least one bearing is disposed between the rotatable drum assembly and the frame, and further wherein one race of the bearing is formed by a surface of the rotatable drum assembly and the other race of the bearing is formed by a surface of the frame; an X-ray tube mounted on the rotatable drum assembly; and an X-ray detector mounted on the rotatable drum assembly in alignment with the X-ray beam; and a transport mechanism mounted to the frame, the transport mechanism comprising a fine movement mechanism for moving the CT imaging unit precisely, relative to the patient, during scanning.
