1. A computed tomography (CT) apparatus comprising:
a gantry including a rotation device which has a ring shape and is rotatable about an axis of rotation;
a plurality of light sources provided at regular intervals on the rotation device and configured to emit X-rays to a subject;
at least one detector provided on the 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:
rotate the rotation device in a first rotation direction by an angle of rotation determined based on a total number of the plurality of light sources;
emit X-rays to the subject alternately from the plurality of light sources in a predetermined order in a unit of a unit angle and detect X-rays passing through the subject by the at least one detector during the rotation of the rotation device in the first rotation direction; and
rotate the rotation device by the determined rotation angle in a second rotation direction opposite to the first rotation direction.
