1. A method of generating a three-dimensional geometric model of an anatomical region, the method comprising:
defining a three-dimensional voxel space comprising a plurality of voxels; receiving a plurality of two-dimensional echographic image slices of the anatomical region, wherein each image slice of the plurality of image slices is associated with localization information;
assembling the plurality of two-dimensional echographic image slices of the anatomical region into a three-dimensional geometric model of the anatomical region using the associated localization information;
graphically outputting the three-dimensional geometric model of the anatomical region in the three-dimensional voxel space; and
graphically representing data sufficiency of the three-dimensional geometric model of the anatomical region, wherein graphically representing data sufficiency of the three-dimensional geometric model of the anatomical region comprises outputting a one-dimensional illustration of the data sufficiency of the three-dimensional geometric model.
