    Abstract: A computer-assisted method for detecting surface features in a virtual colonoscopy. The method includes providing a three-dimensional construction of a computed tomography colonography surface; creating a path along the teniae coli from the proximal ascending colon to the distal descending colon on the colonography surface; forming an indexed computed tomography colonography surface using the created path; and registering the supine and prone scans of the computed tomography colonography surface using the indexed computed tomography colonography surface. The method also includes navigating the internal surface of the computed tomography colonography using the indexed computed tomography colonography surface.

    Abstract: The present invention discloses a method for generating a bone mask. The method comprises the following steps: performing a noncontrast computed tomography scan on a subject in axial mode to get a first data set; after the subject injected with a contrast medium, performing a postcontrast computer tomography angiography scanning on the subject in helical mode to get a second data set; reconstructing the two mentioned data set to acquire a first reconstruction image and a second reconstruction image respectively; resampling the first reconstruction image based on the second reconstruction image by using a computer to get a third reconstruction image; and thresholding values of data which are greater than or equal to a scheduled Hounsfield unit in the third reconstruction image to get a bone mask.
