Abstract
A tomosynthesis scanning system includes an X-ray emitter connected to a first robotic device, and an X-ray detector connected to a second robotic device. The first robotic device moves the emitter along a first spiral trajectory path and, optionally, the second robotic device moves the detector along a second spiral trajectory path during the scanning process. Where both the emitter and detector move, the movement is synchronized. A computer is used to control the first and second robotic devices. In operation, an object to be scanned is positioned between the X-ray emitter and the X-ray detector, then the X-ray emitter is moved along a first spiral path while emitting a photon beam at the X-ray detector and allowing the photon beam to pass through the object before reaching the X-ray detector. Attenuation of the photon beam reaching the X-ray detector is measured and an image is produced based on the measured attenuation of the photon beam.
