An apparatus and method for generating a data set representation of an object or tissue are described. Two image representation data sets for the object or tissue are generated by a CT or MRI scan or other known imaging process. The second data set is preferably generated with enhanced contrast between background tissue and the target tissue of interest, e.g., blood vessels, such as by the injection of a vascular contrast enhancing agent. The first data set is viewed as the union of plural data value neighborhoods, with each neighborhood preferably surrounding a central data value. Each data value of the second data set is compared to a neighborhood in the first data set. If a data value in the second data set is incompatible with the neighborhood, then it is concluded that the data value in the second data set is representative of contrast-enhanced target tissue and is therefore used to generate the final image data set of the target tissue. |
