1. A computed tomography (CT) apparatus comprising:
a gantry including a first rotation device and a second rotation device which have a ring shape, share an axis of rotation, and are rotatable independently of each other;
a plurality of light sources provided at regular intervals on the first rotation device and configured to emit X-rays to a subject;
a detector provided on the second rotation device and configured to detect X-rays passing through the subject and surround inner sides of the second rotation device; and
one or more processors,
wherein the one or more processors are configured to:
rotate the first rotation device in a first rotation direction by an angle of rotation determined based on a total number of the plurality of light sources;
control the plurality of light sources to sequentially and alternately emit X-rays to the subject in units of a unit angle according to a predetermined order and detect X-rays passing through the subject by the detector during the rotation of the first rotation device in the first rotation direction or a second rotation direction opposite to the first rotation direction; and
rotate the first rotation device by the determined angle of rotation in the second rotation direction.
