A system and method for managing imaging data related to a biological trait, including generating a three-dimensional representation of the external surface of the body a patient; obtaining the imaging data; associating the imaging data with a coordinate location of the three-dimensional representation, to generate an associated imaging data; and managing the associated imaging data using the surface representation. The association includes uniquely associating numerical values (e.g., Cartesian coordinates) to particular surface features. The three-dimensional model includes the ability to adjust the pose of the 3D models made from data taken at different times so that the coordinate systems closely correspond.
