Patent ID: 8681933

Claim:
An X-ray computed tomography apparatus comprising: an X-ray tube configured to generate X-rays; an X-ray detector configured to detect the X-rays generated from the X-ray tube and transmitted through an object; a top on which the object is placed; a rotation driving unit configured to rotate a rotating frame around the object, wherein the X-ray tube and the X-ray detector are mounted on the rotating frame; a movement driving unit configured to relatively reciprocate the rotating frame and the top over a plurality of times along a long-axis direction of the top; and a scan control unit configured to control the movement driving unit in relative reciprocal movement of the rotating frame and the top to coordinate a first plurality of moving loci of the X-ray tube with a first plurality of respective forward movements of at least one of the top and the rotating frame, and to coordinate a second plurality of moving loci of the X-ray tube with a second plurality of respective backward movements of at least one of the top and the rotating frame.
