摘要： Typically, a dual layer multi-spectral X-ray detector is capable of providing two points of spectral data about an imaged sample, because the front X-ray detector also acts to filter part of an incident X-ray spectrum before detection by a rear X-ray detector. A pre- filter can be placed in front of the front X-ray detector to enhance the spectral separation. However, the provision of a pre-filter implies that the intensity of the X-ray radiation must be increased to achieve the same signal to noise ratio. The present application concerns a multi-spectral X-ray detector with a front X-ray detector, a rear X-ray detector, and a structured spectral filter placed in-between them. The structured spectral filter has first and second regions configured to sample superpixels of the front X-ray detector, enabling three separate items of spectral information to be obtained per superpixel.

摘要： The invention relates to peripheral equalization during a mammography X-ray examination. High contrast tissue pixel values are removed from the background estimate by finding the minimum intensity values of the pixel located in the neighbourhood, which have approximately the same distance to the skin line. Thus, high attenuating pixel values may be removed from the estimate and replaced by lower attenuating tissue pixel values. After a minimum filtration, a conventional peripheral equalization is performed. This may result in less overshoots and intensity values for higher attenuating structures in the peripheral region may become more consistent with intensity values for higher attenuating structures in the fully compressed region.

摘要： The invention relates to beam hardening correction in X-ray Dark-Field imaging of a subject including a first material and a second material, the first and second material having different beam hardening properties. As the X-ray imaging data includes information on the internal structure of the imaged subject, such information may be used, together with appropriate calibration data to identify the beam hardening contributions occurring in the imaged area of the subject, so to allow for a correction of artifacts due to beam hardening in X-ray Dark-Field imaging.
