Abstract: An apparatus and method for imaging a breast are provided. The apparatus includes an X-ray emission unit that emits an X-ray of a first energy spectrum and an X-ray of a second energy spectrum from above a first region of a breast and emits an X-ray of a third energy spectrum from above a second region of the breast different from the first region of the breast; an X-ray detection unit that generates a plurality of image frames related to the breast by detecting the X-rays emitted and passed through the breast; and an image generation unit that generates image data related to the breast by combining the plurality of image frames.
