ABSTRACT:
A computerized tomography system is provided with a gantry that is rotatable in an X-Y plane transverse to a Z reference axis. The gantry has an opening through which a support on a couch is linearly movable along the Z-axis. An X-ray source directs rays across the gantry opening to a pair of arrays of X-ray detectors. Doing a rapid scan the gantry is rotated as the support is moved linearly so that a helical path is followed by the X-ray source. The resultant dual array data is combined and processed to generate successive quality X-Y planar images.
