Abstract

A method of determining direct x-ray exposure regions in digital medical imaging comprising the steps of: providing a digital medical image including a matrix of lines and columns of pixels; evaluating significant transitions in line and column profiles to determine appropriate line and column thresholds; evaluating all pixels which exceed the line/column threshold for structure by computing the variation within a moving window using a range statistic; accumulating within a histogram pixels which exceed a threshold for that particular line or column and which contain variation indicative of direct x-ray exposure; and analyzing the background histogram to determine the beginning intensity or code value (left point) of the background region.
