Abstract
A radiation detection system of an imaging system (100) includes a radiation sensitive detector array (112). The array includes a detector pixel with an optically transparent encapsulate material (114) with one or more particles (116) supporting one or more different scintillation materials (118), wherein each scintillation material is in the form of a nanometer to micrometer quantum dot. A method includes receiving radiation with a detector pixel, wherein the detector pixel includes an encapsulate with one or more quantum dots, wherein each of the quantum dots includes a scintillation material, generating, with the detector pixel, a signal indicative of the received radiation, and reconstructing the signal to construct an image.
