The present invention is a system and method for visually indexing medical data about a patient by generating an image for presentation to a user depicting a subset of the patient's body parts, with body parts having associated diagnostic data highlighted. A user may then select a highlighted body part and be presented with some or all of the associated diagnostic data. The user may manipulate the presented image, which is derived from a three dimensional model, to rotate it or zoom is to expose more body parts, or more detailed body parts depicting child body parts associated with the diagnostic data. The system or method may employ a patient index comprising a hierarchical graph with nodes corresponding to body parts and associated with diagnostic data for those body parts.
