ABSTRACT:
Methods and systems for performing a tomographic scan which allow an operator to define a non-circular orbit so that a detector can be positioned close to a patient at each view are described. Such methods and systems provide that the patient to detector distance is reduced, which improves spatial resolution for the scan. In one embodiment, and to achieve a non-circular orbit, the camera and table/patient are moved with respect to one another. Specifically, the table is pinned in position and set to lateral and vertical positions during set-up. The same lateral and vertical table positions are maintained during the scanning phase. To get the camera closer or farther from the patient/table, the camera is pitched in or out. The camera head is tilted to achieve a tilt angle of zero degrees for all changes in pitch. As the camera pitches in and out, the central axis of the camera moves along the longitudinal axis of the table. To compensate for movement of the camera central axis, the table is extended or retracted longitudinally.
