ABSTRACT:
A rotating gantry (20) is rotatably mounted to a stationary gantry for rotation around an axis of rotation. Gamma camera detector heads (22a, 22b, 22c) are mounted to the rotating gantry for rotation about a patient receiving region (14). A patient is supported on a first, cantilevered patient support portion (10) which is adjustable in height, and which selectively extends toward and away from a slab defined by the detector heads. In one mode of use, the first patient support portion (10) is supported on a second support surface (16) when fully cantilevered to minimize vibration and movement. In a second mode, the first patient support portion (10) is separated by a gap from the second support portion (16) and the region of interest of the patient is positioned over the gap. In this manner, radiation passing from the region of interest of the patient to the detector heads is not attenuated by a patient support structure. Further, the detector heads are mounted on tracks (30, 32) by rollers (44, 46). A linear motor (34) selectively moves each detector head along the tracks to change its circumferential position relative to the other detector heads. The movable detector head is further connected with pads (58) which slidably engage opposite faces of the tracks to prevent wobble and vibration.
