METHOD AND APPARATUS FOR REDUCING PHOTOCONDUCTION EFFECT IN APPLICATION OF DUAL ENERGY TO SEMICONDUCTOR DIGITAL X-RAY DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for reducing photoconductive effect of a semiconductor digital X-ray detector in an energy medical diagnosing imaging system.;SOLUTION: A detector 110 is exposed to a first irradiation 610 from an energy source 120, and a first image data set is acquired for a first read time 630 by the first irradiation 610 after a first delay 620. In this method, the detector 110 may be exposed to a second irradiation 616 from the energy source 120 to acquire a second image data set for a second read time 635 by the second irradiation 616 after a second delay 625, wherein the first delay 620 is less than the second delay 625 and the first read time 630 is shorter than the second read time 635.;COPYRIGHT: (C)2002,JPO
