<p>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. In a preferred embodiment the carousel includes two linear motion positioning tables (24) and one rotary motion positioning table (34) as part of a positionable mounting for moving the patient platform in three degrees of motion. A programmed computer controls (16) the motion of the carousel about a predetermined locus of points. The method includes positioning the carousel in a 'home' position, placing a patient in the carousel and manually positioning the patient platform to a desired close position with respect to a stationary radiation detector (18). The position is then recorded in the memory of a control computer and the procedure is repeated to obtain the desired number of radii of the patient's organ of interest to the detector.</p> |
