Abstract
A tomogram is obtained by tomosynthesis in a high speed CT scanning system in which fan beams of radiation are generated by sweeping an electron beam along a target, and collimated X-rays emitted by the target are received by an array of detectors after passing through a patient area between the target and array of detectors. The patient is moved through the collimated x-rays as the measurments are obtained, and the measurements are time-correlated to correspond to data measurements for a plurality of projection radiographs. The measurements for the plurality of radiographs are combined to tomosynthesize a tomogram at a selected plane in the patient.
