X-ray imaging apparatus and control method therefor

Abstract

Disclosed herein are an X-ray imaging apparatus and a control method therefor in which a region of a compressed breast is measured by a touch sensor and a collimator is controlled such that an X-ray emission region corresponds to the measured region of a compressed breast, whereby workflow for performing X-ray imaging may be reduced and subject pain due to breast compression may be alleviated. The X-ray imaging apparatus includes an X-ray source to generate X-rays and irradiate an object with the generated X-rays, a collimator to adjust an emission region of the X-rays generated from the X-ray source, an X-ray detector to detect X-rays having passed through the object to acquire X-ray data, a touch sensor disposed above the X-ray detector, a compression paddle to compress the object placed on the touch sensor, and a collimator control unit to calculate location and size of the compressed object based on an output value of the touch sensor and control the collimator based on calculation results.
