<p>A nuclear camera system includes oppositely disposed radiation detectors (10a, 10b) which view an examination region 14 wherein a subject 16 is received therein. During a diagnostic scan, a motor and drive assembly (18) concurrently moves the detectors (10a, 10b) in a straight path along a longitudinal axis (20) for a selected time interval. The radiation detectors (10a, 10b) are positioned at a first angle at which the subject is viewed and the angle is maintained through the scan. A data processor (23) collects the data from the detected radiation and a coincidence circuitry (26) determines coincidence radiation events occurring on the detectors 10a, 10b. A first set of image data is generated for the first angular view and stored in a view memory (28). A second scan is performed where the detectors (10a, 10b) are shifted to a second angular view and the detectors are moved along the longitudinal axis for a second selected time interval. Radiation data is collected and a second set of image data is generated for the second scan. The first and second sets of image data are combined and a reconstruction processor (50) reconstructs the combined data into an image representation or a whole-body tomographic image (60). <IMAGE></p> |
