Abstract:
A method of identifying an object represented computed tomography (CT) data for a region comprising:identifying a plurality of volume elements for the region in the CT data, each volume element being associated with a density value;identifying a first density range and a second density range;for each of the plurality of volume elements, comparing the density value of the volume element with at least one of the density ranges;if the density value of the volume element is within one of the density ranges, labeling the volume element as being associated with an object of interest; andfor each volume element labeled as being associated with an object of interest, (i) computing a difference between the density value of the volume element and the density value of a neighboring volume element, and (ii) if the difference between the density value of the volume element and the density value of the neighboring volume element is below a predetermined difference threshold, combining the volume element and the neighboring volume element into a single object.
