Abstract:
1. A method for a minimizing artifacts and total exam time between acquisitions in dual or multiple energy imaging, the method comprising: (a) exposing a detector to a first exposure from an energy source at a first energy dosage during a first exposure interval; (b) after said first exposure interval, obtaining a first image data set during a first read time; (c) after said first read time, exposing said detector to a second exposure from said energy source at a second energy dosage during a second exposure interval; (d) after said second exposure interval, obtaining a second image data set during a second read time; (e) after said second read time, scrubbing said detector; (f) after said scrubbing, obtaining a first offset image from said detector; (g) after said obtaining said first offset image, obtaining a second offset image from said detector; (h) applying said first offset image to compensate for charge retention effects in said first image data set; and (i) applying said second offset image to compensate for charge retention effects in the second image data set.
