<p>An x-ray scanning imaging apparatus with a generally O-shaped gantry ring, which has a segment that fully or partially detaches (or 'breaks') from the ring to provide an opening through which the object to be imaged may enter interior of the ring in a radial direction. The segment can then be re-attached to enclose the object within gantry. Once closed, the circular gantry housing remains orbitally fixed and carries an x-ray image-scanning device that can be rotated inside the gantry 360 degrees around the patient either continuously or in a step-wise fashion. The x-ray device is particularly useful for two-dimensional and/or three-dimensional computed tomography (CT) imaging applications.</p> |
