Abstract

Described embodiments include a system, method, and computer program product. In a described system, a receiver circuit receives at least two reference images of a patient body part. Each reference image includes a respective landmark subsurface feature of the patient body part, and each imaged landmark subsurface feature has a respective spatial relationship to a respective region of a surface of the patient body part imaged during a medical examination. A feature matching circuit determines a correspondence between (x) each atlas landmark subsurface feature of the patient body part included in a landmark subsurface feature atlas and (y) each respective imaged landmark subsurface feature. A reporting circuit generates informational data reporting a depiction of an area of the surface of the patient body part by at least two adjacent imaged regions of the surface of the patient body part. A communication circuit outputs the informational data.
