Abstract:
1. A method of formatting data for detecting colon polyps in a Computed Tomography Colonography (CTC) dataset using a computer processing apparatus for providing automated image analysis, said method comprising the steps of: i) using the computer processing apparatus to receive the CTC dataset and using the computer processing apparatus to extract colon surface data, from the CTC dataset, within a sub-volume of the extracted colon surface data that is centered on a seed point of a candidate polyp; ii) using the computer processing apparatus to identify individual sets of points corresponding to a body of the candidate polyp and a base of the candidate polyp within the sub-volume; iii) using the computer processing apparatus to select the points corresponding to the body; iv) using the computer processing apparatus to re-format the candidate polyp by projecting the selected points corresponding to the body on to a tangent plane, wherein re-formatting of the candidate polyp includes the following steps carried out by the computer processing apparatus: v) using the computer processing apparatus to generate a series of cutting planes based on the reformatted candidate polyp.
