Abstract
Method, apparatus and system for reducing or preventing polarization in semiconductor radiation detectors for medical imaging. For example, an apparatus includes a semiconductor with electrodes coupled thereto, configured to generate an electrical signal in the electrodes in response to absorption of ionizing radiation in the semiconductor, wherein the absorption of the ionizing radiation generates a space charge in the semiconductor; and an infra-red (IR) generator configured to generate IR radiation of a selectable wavelength, the selectable wavelength being chosen so as to at least partially reduce an effect of the space charge on the electrical signal.
