Abstract

The invention is directed toward two-dimensional dynamic body image templates, and associated techniques, that allow a user to indicate regions of the human body. The body region indications may correspond to locations of injury, pain, treatment, discoloration, paresthesia, or the like. A user is presented with the body image templates and asked to indicate regions on the body templates that correspond to affected regions of a patient'"'"'s body. The body image templates represent views of an external surface of a human body rotated about at least one axis. In exemplary embodiments, a user controls display of overlapping templates, which may allow the user to perceive rotation of a three-dimensional body surface. The user indicated regions from each of the displayed body image templates are stored in a body surface coordinate system, such that regions indicated via one template may be appropriately displayed on other templates.
