1. A method for segmenting a target anatomy in a 3D ultrasound volume, the method comprising:
obtaining a scan-converted ultrasound volume within a scan-converted space in a Cartesian coordinate system;
transforming the scan-converted ultrasound volume to a de-scanned ultrasound volume within a de-scanned space in a Toroidal coordinate system, wherein the de-scanned ultrasound volume comprises an estimate of the ultrasound volume as obtained by an original acquisition procedure; and
performing a segmentation of a target anatomy on the ultrasound volume in the de-scanned space to generate segmentation data.
