Abstract
In the illustrated embodiment, each detector is reciprocally mounted for movement from a retracted position clear of the X-ray beam into an operative position. For a fan-shaped X-ray beam which is shifted by activating successive electron sources arranged about a ring anode, successive sets of detectors are activated, always on the opposite side of the patient location from the active focus. As a specific example, successive sets of electromagnets may be activated by an electronic stepping circuit to provide one-degree shifts in the active set of detectors.
