1. A computer-implemented method of orientating and displaying a three-dimensional (3-D) representation of an upper torso in an automatic fashion, comprising the method steps of: (a) recognizing a plurality of 3-D features and locations of said upper torso from said 3-D representation of said upper torso; (b) determining an upper torso midline defined by at least one of said recognized 3-D features and locations; (c) determining a coronal plane of said upper torso defined by at least two of said recognized 3-D features and locations; and (d) rotating and displaying said 3-D representation of said upper torso on a display such that said coronal plane of said upper torso coincides with the view plane of said display, and such that said upper torso midline is parallel to the vertical axis of said display.
