Scanning-beam x-ray imaging system

摘要

An x-ray imaging system according to the present invention comprising a stepped scanning-beam x-ray source (10) and a multi-detector array (110). The output of the multi-detector array is input to an image reconstruction engine which combines the outputs of the multi-detectors over selected steps of the x-ray beam to generate an x-ray image of the object (80). A collimating element (90), preferably in the form of a perforated grid containing an array of apertures (140), interposed between the x-ray source (10) and an object (80) to the x-rayed. A multi-detector array assembly (110) comprising alignment components. A maneuverable positioner incorporating an x-ray sensitive marker allowing the determination of the precise position coordinates of the maneuverable positioner.
