1. A method for producing a model of bone geometry of a volumetric region of a body, the method comprising the steps of:
- a) scanning the volumetric region using ultrasound and acquiring geometric data associated with bones within the volumetric region;
b) identifying points from the acquired data that are derived from a surface of the bones;
c) organizing the points into separate bone entities representing the bones of the volumetric region; and
d) transforming the points so as to position the bone entities in accordance with a normalized template.

Abstract
A method for producing a model of bone geometry of a volumetric region of a body is provided. The method comprises scanning the volumetric region using ultrasound and acquiring geometric data associated with bones; identifying points derived from a surface of the bones; organizing the points into separate bone entities and transforming the points so as to position the bone entities in accordance with a normalized template. The model may be used for identifying or verifying the identity of a person.
