1. A method for segmentation of a boundary, the method comprising: detecting, by a processor, a first boundary in a medical image representing a patient, the detecting of the first boundary being a function of an input point; generating, by the processor, a banded graph based on the first boundary; identifying, by the processor, a second boundary with the banded graph; locating, by the processor, a center of an area or volume defined by the second boundary; detecting, by the processor, a third boundary in the medical image as a function of the center; and displaying a second image as a function of the third boundary.
