  • Electronic cleansing of digital data sets
    Patent number: 8472687
    Abstract: A method of processing a 3-dimensional Computed Tomography Colonography data set to remove tagged material is disclosed. The method involves the preliminary processing step of classifying voxels in the data set as corresponding to air, tagged material or colon tissue. Methods of overcoming erroneous classification of Partial Volume air/tagged material interface voxels are disclosed. The present invention also provides for methods of circumventing problems resulting from removal of tagged material from a CTC data set, which can result in the erosion of soft-tissue structures partially covered by tagged colonic fluid.
    Type: Grant
