MINIMIZED DIRECTLY CONVERTED X-RAY EFFECTS ON IMAGERS
摘要
In one embodiment, an image sensor (290) for an x-ray imager (200) includes a photodiode (223) and a readout circuit. A deep well (232) 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.
