Digital Subtraction Bowel Cleansing for CT Colonography Using Morphological and Linear Filtration Methods.

We describe a method to perform postacquisitioil processing of computed tomography colonography (virtual colonoscopy) datasets that results in electronic removal of opacified, ingested bowel contents while reconstructing natural appearing boundaries of colon lumen and thereby permitting three-dimensional visual analyses of the resulting colon models.
