摘要：
An X-ray imaging apparatus includes an X-ray source configured to radiate X-rays onto an object region, an X-ray detector configured to detect the radiated X-rays and obtain image frames of the object region based on the detected X-rays, and a filter configured to filter X-rays radiated from the X-ray source such that the X-rays incident on a region of interest (ROI) of the object region have a lower dose than a dose of X-rays incident on a non-ROI of the object region.
