The invention relates to a system and method for segmenting an image of a plurality of structures stored as a set of spatially related data points. The data points represent variations in a predetermined parameter which allows the segmentation to occur. Once the data is acquired, a seed point is selected indicating a structure of interest. Each of the data points is assigned a value of connectivity as to the confidence that it is part of the same structure of the seed point. An endpoint is selected of the structure of interest and a path is built between the seed point and the end point based on the values of connectivity. Planes are cut along the path and a final connectivity is determined using the data points located on each plane thereby producing a final segmented image.

Abstract

The invention relates to a system and method for segmenting an image of a plurality of structures stored as a set of spatially related data points. The data points represent variations in a predetermined parameter which allows the segmentation to occur. Once the data is acquired, a seed point is selected indicating a structure of interest. Each of the data points is assigned a value of connectivity as to the confidence that it is part of the same structure of the seed point. An endpoint is selected of the structure of interest and a path is built between the seed point and the end point based on the values of connectivity. Planes are cut along the path and a final connectivity is determined using the data points located on each plane thereby producing a final segmented image.
