Abstract: An X-ray apparatus includes: a collimator for adjusting an X-ray irradiation region; a data obtainer for obtaining position information of a target in an object based on an electrode signal sensed from electrodes attached to the object; and a controller for setting first coordinates indicating a position of the target on a first coordinate system with respect to the object based on the position information, transforming the first coordinates to second coordinates on a second coordinate system with respect to an X-ray image of the object, and adjusting a position of the collimator based on the second coordinates.

Abstract: An X-ray apparatus includes a controller controlling generation of an X-ray and adjusting at least one of a plurality of image frames generated based on the X-ray passed through an object, and an X-ray generator generating the X-ray. The X-ray corresponds to a pulse signal including a plurality of pulses, in which at least one of a pulse rate or a pulse amplitude is variable.
