发明名称 X-RAY IMAGE GENERATION
摘要 Generation of an X-ray image of an object using a counting X-ray detector is provided. The X-ray detector includes detector modules that may be aligned adjacent to one another. Each of the detector modules is subdivided into a matrix having a plurality of pixels. The detector modules are arranged adjacent to one another on a common substrate. A sensor surface formed by the detector modules has a uniform matrix structure having a constant pixel pitch. At least one missing pixel is arranged within the sensor surface. Raw image data is acquired by a portion of the detector modules of the X-ray detector, the acquired raw image data is at least partially corrected, and further raw image data is calculated for the at least one missing pixel using the corrected raw image data. The X-ray image is calculated based on the corrected raw image data and the further raw image data.

主权项 1. A method for generating an X-ray image of an object using an X-ray system, the X-ray system comprising a counting X-ray detector, the counting X-ray detector comprising a plurality of detector modules that are alignable adjacent to one another, wherein each detector module of the plurality of detector modules comprises an X-ray converter and is subdivided into a matrix having a plurality of pixels, wherein the plurality of detector modules are arranged adjacent to one another on a common substrate, wherein a sensor surface formed by the plurality of detector modules has a uniform matrix structure having a constant pixel pitch, wherein at least one missing pixel is arranged within the sensor surface, the method comprising: acquiring raw image data using a subset of detector modules of the plurality of the detector modules of the counting X-ray detector; at least partially correcting the acquired raw image data; calculating further raw image data for the at least one missing pixel using the at least partially corrected raw image data; and calculating the X-ray image based on the at least partially corrected raw image data and the further raw image data.
