Claim 0:
1. A computed tomography (CT) apparatus comprising:
a gantry including a first rotation device, a second rotation device, and a third rotation device which have a ring shape, share an axis of rotation, and are rotatable independently of one another;
a plurality of first light sources provided on the first rotation device at regular intervals and configured to emit X-rays to a subject;
a plurality of second light sources provided on the second rotation device at regular intervals and configured to emit X-rays to the subject;
a detector provided on a region of the third rotation device and configured to detect X-rays passing through the subject; and
one or more processors,
wherein the one or more processors are configured to:
control the first rotation device to repeatedly perform a first operation of being rotated in a first rotation direction by an angle of rotation determined based on a total number of the plurality of first light sources and a total number of the plurality of second light sources and a second operation of being rotated by the determined angle of rotation in a second rotation direction opposite to the first rotation direction;
control the second rotation device to repeatedly perform a third operation of being rotated by the determined angle of rotation in the second rotation direction and a fourth operation of being rotated by the determined angle of rotation in the first rotation direction;
control the third rotation device to be rotated in the first rotation direction at a same speed of rotation as the first rotation device and the second rotation device while the first rotation device repeatedly performs the first operation and the second operation and the second rotation device repeatedly performs the third operation and the fourth operation;
emit X-rays to the subject from one of the plurality of first light sources during the performance of the first operation by the first rotation device and emit X-rays to the subject from one of the plurality of second light sources during the performance of the fourth operation by the second rotation device; and
detect X-rays passing through the subject by the detector.
