  • Method of recognizing an irradiation field
    Patent number: 5506913
    Abstract: Radiologists may protect their subjects against unnecessary exposure to X-rays by use of X-ray opaque material. The resulting image contains relatively unexposed regions which comprise the shadow cast by the X-ray opaque material. This invention discloses a method for the automatic determination of the location of the boundary between signal and shadow regions. Many hypotheses as to the location of the boundary are generated and the final decision as to the correct hypothesis is contingent on the results of a number of high-level tests applied to each.
