NANO-MATERIAL IMAGING DETECTOR WITH AN INTEGRAL PIXEL BORDER

A radiation detector array (112) of an imaging system (100) comprises a plurality of detector modules (114). Each of the plurality of detector modules includes a plurality of detector pixel (116). Each of the plurality of detector pixels includes an integral pixel border (202, 204, 206,208) and a direct conversion active area within the integral pixel border. A method comprises receiving radiation with a nano-material detector pixel that includes an integral pixel border, generating, with the detector pixel, a signal indicative of an energy of the received radiation, while reducing pixel signal crosstalk, and reconstructing the signal to construct an image. An imaging system (100) comprises a source of X-ray radiation configured to emit X-ray radiation that traverses an examination region, a nano-material imaging detector with an integral pixel border, wherein the nano-material imaging detector is configured to detect X-ray radiation, and a reconstructor configured to reconstruct an output of the nano-material imaging detector to produce a CT image.
