X-ray imaging system and x-ray imaging method

Abstract

The X-ray imaging system includes a camera unit, a display unit, an input unit, an exposure assembly, and a control unit. The camera unit is configured to acquire a real-time optical image of a subject under examination. The display unit is configured to display the real-time optical image. The input unit is configured to receive a user operation and to form a target region on the user interface by changing the position of a center of the collimation region. The exposure assembly includes an X-ray source, a detector, and a collimator, the collimator having an opening configured to display a collimation region on the subject under examination. The control unit is configured to control movement of the X-ray source and the detector to align with the center of the target region, and control the opening of the collimator such that the collimation region is aligned with the target region.
