We have mapped three-dimensional (3-D) structure to determine details of surface profiles of the ear canal.
We have developed an optical scanner for inner surface profile measurement. The 3-D mapping of
the ear canal between our method and a micro-focus x-ray CT system has been also compared. Our research
provides 3-D mapping to determine surface profiles from the eardrum to auricle, without using
impression materials.
