<p>The present invention relates to the field of medical imaging and, particularly, to an apparatus for selecting X-ray energy spectrum. Said apparatus comprises an X-ray tube, and further comprises a reflective film filtering mirror, wherein said reflective light film filtering mirror is arranged to form an included angle between its surface and the propagation direction of an X-ray beam emitted by said X-ray tube, so as to reflect the X-rays in a predetermined energy band, thus, achieving the energy spectrum selection of the X-ray beam, which provides a new way of imaging and a new application extension field for the X-ray imaging while improving the signal-to-noise ratio.</p> |
