Abstract: An embodiment of the present invention provides a radiation therapy device including: a main body; a gantry coupled to a side of the main part and rotatable relative to the main part in at least one direction; a radiation head provided on a side of the gantry to emit radiation; an image acquisition unit facing the radiation head to detect radiation emitted from the radiation head and obtain images by converting the detected radiation into electric signals; and a reference image acquisition frame provided on a side of the radiation head and including a plurality of markers formed thereon.

Abstract: Provided is a radiation therapy apparatus on which quality management is performed. The radiation therapy apparatus includes: a body unit; a gantry coupled to one side of the body unit and formed to be rotatable in at least one direction with regard to the body unit; a radiation irradiating head formed at one side of the gantry to irradiate a radiation; and a level control module formed at one side of the radiation irradiating head to measure a rotation angle of the gantry or the radiation irradiating head, compare the measured rotation angle with a rotation angle indicated by an angle indicator of the radiation therapy apparatus, and correct an error of the angle indicator.
