Abstract:
1. A method for collecting x-ray exposure data in an x-ray detector including: providing an x-ray detector including a plurality of pixels grouped into a plurality of data lines each extending from opposite detector edges to a data line split; placing an anatomy to be examined between said detector and said x-ray source so that a region of interest of said anatomy includes at least a portion of said data line split; exposing said x-ray detector and said anatomy to an x-ray flux, wherein one or more of said data lines includes unsaturated pixels and saturated pixels, said saturated pixels having a larger amount of electric charge depleted than said unsaturated pixels, said unsaturated pixels located within said region of interest and said saturated pixels located outside of said region of interest; scanning said plurality of pixels by activating said pixels in each of said data lines in a progression from each of said opposite detector edges towards said data line split; and measuring an amount of electric charge depleted in said unsaturated and said saturated pixels, wherein said scanning causes said saturated pixels to be scanned before said unsaturated pixels in one or more of said data lines.
