Abstract
A two dimensional radiograph or a continuously rotating two dimensional radiograph of a patient is obtained using a high speed CT scanning system in which fan beams of radiation are generated by sweeping an electron beam along a target. Collimated X-rays emitted by the target are received by an array of detectors after passing through a patient area between the target and the array of detectors. A single detector position, comprising one or more detectors, can be employed to obtain a single two dimensional projection radiograph. Alternatively, a plurality of detector positions can be employed in measuring radiation and obtaining a continuously rotating two dimensional projection radiograph.
