Abstract: An imaging system for imaging an object, the imaging system comprising: a housing having a center opening; a CT imaging unit mounted to the housing, the CT imaging unit comprising: a rotatable disc extending around the center opening; an X-ray emitter mounted to the rotatable disc and configured to emit an X-ray beam; and an X-ray detector mounted to the rotatable disc in alignment with the X-ray beam; and a digital radiography imager comprising a detector plate mounted to the rotatable disc, the detector plate being configured to assume (i) a retracted position in which the detector plate is not aligned with the X-ray beam, whereby to permit the X-ray beam to contact the X-ray detector, and (ii) an extended position in which the detector plate is aligned with the X-ray beam, whereby to permit the X-ray beam to contact the detector plate.

Abstract: A method for correcting inaccuracies in a three-dimensional (3D) rendered volume of an object due to deviations between an actual scanner translation speed and an expected scanner translation speed, the method comprising: placing a pre-measured reference adjacent to the object which is being scanned so that the pre-measured reference and the object are in the same scan field; scanning the object and the pre-measured reference so that the object and the pre-measured reference are both incorporated in a 3D rendered volume produced through scanning; comparing the 3D rendered volume of the pre-measured reference against the 3D volume of the true pre-measured reference and generating a correction map indicative of how the rendered 3D volume of the pre-measured reference should be adjusted so as to produce a more accurate 3D rendering of the pre-measured reference; and using the correction map to adjust the rendered 3D volume of the object.

Abstract: A new and improved anatomical imaging system which includes a new and improved movement system, wherein the movement system comprises an omnidirectional powered drive unit and wherein the movement system can substantially eliminate lateral walk (or drift) over the complete stroke of a scan, even when the floor includes substantial irregularities, whereby to improve the accuracy of the scan results and avoid unintentional engagement of the anatomical imaging system with the bed or gurney which is supporting the patient.

Abstract: Methods for the correction of drive, tilt, and scanning-speed errors in imaging systems such as CT machines.
