Robust Cochlear Modiolar Axis Detection in CT

Wilhelm Wimmer, Clair Vandersteen, Nicolas Guevara, Marco Caversaccio & Hervé Delingette
The cochlea, the auditory part of the inner ear, is a spiral-shaped organ with large morphological variability. An individualized assessment of its shape is essential for clinical applications related to tonotopy and cochlear implantation. To unambiguously reference morphological parameters, reliable recognition of the cochlear modiolar axis in computed tomography (CT) images is required. The conventional method introduces measurement uncertainties, as it is based on manually selected and difficult to identify landmarks. Herein, we present an...
