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.

摘要: An x-ray detector (60), useful in x-ray imaging systems comprising a plurality of detector elements (608) comprising a plurality of detector sub-elements (612). A plurality of X-ray detectors (608) are arranged in a multi-dimensional array (604), each array of detectors tiered (310) with respect to the next array of detectors. A compact electronics circuitry (800) is contained in each of the plurality of detector sub-elements (608). The compact electronics circuitry comprises a photon sensor (804), an amplifier (808), a discriminator (812) and an analog-to-digital converter (824). Finally, a method for generating X-ray transmissiveness information is also provided.
