摘要: X-rays passing through the beating heart or bone can create error in standard computer tomographic scans of organs around these regions. Often doctors are interested imaging only surrounded regions, not regions themselves. The author's algorithm reconstructs metal without using that error. Reconstructions mathematical phantoms this given, and a description completed is presented. A explanation given for difficulties inherent any tomography problem with incomplete data. It predicts weaknesses all reconstruction algorithms use
