Claim 10:
11. A computed tomography (CT) method performed by a CT apparatus including a gantry with a first rotation device, a second rotation device, and a third rotation device that have a ring shape, share an axis of rotation, and are rotatable independently of one another, a plurality of first light sources arranged on the first rotation device at regular intervals and configured to emit X-rays to a subject, a plurality of second light sources arranged on the second rotation device at regular intervals and configured to emit X-rays to the subject, and a detector provided on a region of the third rotation device and configured to detect X-rays passing through the subject, the CT method comprising:
controlling 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;
controlling 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;
controlling the third rotation device to be rotated in the first rotation direction at the same speed of rotation as the first rotation device and the second rotation device;
emitting 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 emitting 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
detecting X-rays passing through the subject by the detector.
