EMISSION TOMOGRAPHY CAROUSEL SYSTEM AND METHOD

摘要

An emission tomography carousel system (10) and method for use with a stationary radiation detector (18) in Single Photon Emission computer Tomography (SPECT) (20) procedures is disclosed. Preferably, the carousel includes two linear motion positioning tables (26 and 28) and one rotary motion positioning table (34) as part of a positionable mounting for moving the patient platform 14 in three degrees of motion. A programmed computer (16) controls the motion of the carousel about a predetermined locus of points. The method includes a patient in the carousel and manually positioning the patient pIatform to a desired close position with respect to detector (18). The position is then recorded in the computer memory and the procedure is repeated to obtain the desired number of radii to the detector while keeping the patient's organ of interest in substantially the center of the locus of positions.
