A METAL ARTIFACT REDUCTION ALGORITHM IN CT USING MULTIPLE PRIOR IMAGES BY RECURSIVE ACTIVE CONTOUR SEGMENTATION.

A metal artifact reduction algorithm in CT using multiple prior images by recursive active contour segmentation.

puddles the platypus chocolate We propose a novel metal artifact reduction (MAR) algorithm for CT images that completes a corrupted sinogram along the metal trace region.When metal implants are located inside a field of view, they create a barrier to the transmitted X-ray beam due to the high attenuation of metals, which significantly degrades the
