  • Spectral filtration of X-rays for energy-selective X-ray imaging
    Patent number: 10182774
    Abstract: A filter is disclosed for the spectral filtration of X-rays emanating from an X-ray source which cross an object under examination and are detected by an X-ray detector in at least two different spectral regions. After crossing the object under examination, the X-rays have an energy spectrum which displays a characteristic distribution for the anode material of the X-ray source. In an embodiment, the filter is configured to suppress part of the energy spectrum comprising the focal point of the energy spectrum. A corresponding X-ray system and method are also disclosed.
