The CT scanning system of the present invention includes a source and
detector mounted to a c-arm. The c-arm is positioned on a mounting plate
and ball screw to rotate about an axis centered within the c-arm and to
also translates along the axis of rotation. A computer controls the
rotation of the CT scanner, the x-ray source, and collects the data from
the detector to create an image. The CT scanner first takes a scout scan
prior to the full acquisition of the data. The scout scan is a single
two-dimension image. The CPU draws locating marks on the scout scan image
to indicate the desired location. When proper alignment is verified, the
processor then controls the motor to perform one complete revolution of
the c-arm, during which time the computer collects multiple images from
the detector.
