Abstract
Systems and methods are provided for a detector for medical imaging. The detector for medical imaging includes a mesh detector element formed on a planar side of a first semiconductor layer. The mesh detector element includes a metal layer including a plurality of longitudinal strips, where each longitudinal strip is positioned over a respective second semiconductor layer of the opposite doping polarity from the first semiconductor layer, and embedded in the first semiconductor layer. Further, each longitudinal strip is separated from a neighboring longitudinal strip by a respective opening of a plurality of openings, such that the metal layer does not extend continuously across a width of the mesh detector element.
