    Abstract: 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.

    Abstract: The invention relates to an analyzing grid for phase contrast imaging and/or dark-field imaging, a detector arrangement for phase contrast imaging and/or dark-field imaging comprising such analyzing grid, an X-ray imaging system comprising such detector arrangement, a method for manufacturing such analyzing grid, a computer program element for controlling such analyzing grid or detector arrangement for performing such method and a computer readable medium having stored such computer program element. The analyzing grid comprises a number of X-ray converting gratings. The X-ray converting gratings are configured to convert incident X-ray radiation into light or charge. The number of X-ray converting gratings comprises at least a first X-ray converting grating and a second X-ray converting grating. Further, the X-ray converting gratings each comprise an array of grating bars, wherein the grating bars within each X-ray converting grating are arranged mutually displaced from each other in a direction perpendicular to the incident X-ray radiation by a specific displacement pitch. Further, the grating bars of the first X-ray converting grating are arranged mutually displaced from the grating bars of the second X-ray converting grating in the direction perpendicular to the incident X-ray radiation by the displacement pitch divided by the number of X-ray converting gratings.

    Abstract: A detector includes a first detection layer (1141) and a second detector layer (1142). The first and second detection layers include a first and second scintillator (204, 7041) (216, 7042), a first and second active photosensing region (210, 7081) (220, 7082), a first portion (206, 7261) of a first substrate (208, 7061), and a second portion (218, 7262) of a second substrate (208, 7062). An imaging system (100) includes a radiation source (110), a radiation sensitive detector array (108) comprising a plurality of multi-layer detectors (112), and a reconstructor (118) configured to reconstruct an output of the detector array and produces an image. The detector array includes a first detection layer and a second detector layer with a first and second scintillator, a first and second active photosensing region, a first portion of a first substrate, and a second portion of a second substrate.

    Abstract: The present invention relates to medical imaging, and in particular a medical imaging detector. In order to improve and facilitate the collection of information, e.g. for medical diagnosis, a medical imaging detector is provided that comprises a first sensor arrangement (12) and a second sensor arrangement (14). The first sensor arrangement is configured to provide a first type of image data belonging to a first imaging modality. The second sensor arrangement is configured to provide a second type of image data belonging to a second imaging modality. The first imaging modality is an X-ray imaging modality, while the second imaging modality is a non-X-ray imaging modality. The first sensor arrangement comprises one or a plurality of first sensor segments (16) arranged within a first circumferential line (18) defining a first imaging area (20). The second sensor arrangement comprises one or a plurality of second sensor segments (22) arranged within a second circumferential line (24) defining a second imaging area (26). The first imaging area and the second imaging area at least partly overlap.
