发明名称 X-ray detector with improved quantum efficiency
摘要 Among other things, one or more systems and/or techniques for integrating electrical charge yielded from an indirect conversion detector array of a pulsating radiation system are provided. The integration begins during a resting period between a first and second pulse and ends before the second pulse is emitted. Electrical charge that is measured during a resting period is integrated, while electrical charge measured during a pulse is not integrated. In this way, parasitic contributions caused by the direct interaction of radiation photons with a photodiode are reduced and a quantum efficiency of the indirect conversion detector array is increased, for example. Moreover, the period of integration can be adjusted such that a voltage gain related to the indirect conversion detector array can be varied to a predetermined level.
