Spatially patterned light-blocking layers for radiation imaging detectors
are described. Embodiments comprise spatially patterned light-blocking
layers for an amorphous silicon flat panel x-ray detector, wherein the
spatially patterned light-blocking layer blocks light from a
predetermined number of switching elements in the detector, wherein the
predetermined number comprises less than all of the switching elements in
the detector. These light-blocking layers may block light from each
switching element in a predetermined arrangement of switching elements
that are read out last, or in any other suitable pattern.
