Abstract
In one embodiment, an image sensor for an x-ray imager includes a photodiode and a readout circuit. A deep well formed below the readout circuit may be configured as a diode to drain away parasitic electrons, which would otherwise induce noise in images. The parasitic electrons may be drained away to a power supply or a measuring circuit for dosimetrie purposes, for example.
