Abstract
An X-ray apparatus which aligns an X-ray radiator with an X-ray detector, an X-ray apparatus which aligns an X-ray radiator with an X-ray detector while maintaining a Source to Image-receptor Distance (SID) and a Source to Object Distance (SOD) therebetween, and methods of operating the X-ray apparatuses are provided.
Claims19
An X-ray apparatus comprising:
- an X-ray radiator configured to irradiate an X-ray in a radiation direction;
- an X-ray detector comprising an incidence surface, the X-ray detector being configured to detect the X-ray radiated from the X-ray radiator to the incidence surface;
- a controller configured to:
- acquire first angle information representing an inclination of the X-ray detector,
- acquire second angle information representing an angle by which the X-ray radiator is rotated from a reference position, and
- determine a rotation angle of the X-ray radiator for aligning the X-ray radiator with the X-ray detector of the X-ray radiator based on the first angle information and the second angle information, and a rotation direction of the X-ray radiator based on a motion information corresponding to a motion of the X-ray detector such that a radiation direction of the X-ray radiator is perpendicular to the incidence surface of the X-ray detector;
- of the X-ray detector;
- and
- a driver configured to rotate the X-ray radiator by the rotation angle in the rotation direction.
