Abstract:
1. A method for reconstructing an ear canal, comprising the steps of: providing a set of optical coherence tomography (OCT) scan data of an ear comprising frames and scan lines of pixels that form a 3D data set whose values are interference intensities; extracting frame numbers and line numbers of interference intensities corresponding to one or more markers on an OCT scan guide; receiving reference frame numbers and lines numbers for said one or more markers; determining a starting position and direction for said OCT ear scan from the ear scan marker frame and line numbers and said reference marker frame and line numbers; for each scan line, finding a pixel number of a maximum interference intensity value, and determining an offset distance of said pixel from said scan guide; and reconstructing said surface of said ear canal from said distance offset data.
