Abstract

An imaging apparatus ( 400 ) includes a detector array ( 412 ) with at least one detector tile ( 418 ). The detector tile includes a photosensor array ( 422 ) with a two dimensional array of individual photosensitive detector pixels ( 424 ) located within a non-photosensitive area ( 426 ). The imaging apparatus also includes readout electronics ( 432 ) coupled to the photosensor array and including individual readout channel wells ( 602, 604 ) corresponding to the individual detector pixels. The imaging apparatus also includes an anti-aliasing filter ( 800 ) for a detector pixel that is located in at least one of a region of the photosensor array corresponding to the detector pixel or a region of the readout electronics corresponding to the detector pixel.
