摘要 |
Radiologists may protect their subjects against unnecessary exposure to X-rays by use of X-ray opaque material. They may also use X-ray opaque material to permit multiple exposures on a single image. The resulting image contains relatively unexposed regions resulting from 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 multiple exposures and the boundary between signal and shadow regions within each exposure. Many hypotheses as to the location of such boundaries are generated and the final decision as to the correct hypothesis is contingent on the results of a rule-based reasoning network. <IMAGE> |
