Patient-specific individualization of an electrode array for a cochlear implant

A system for determining a target geometry of an electrode array for a cochlear implant for a patient comprising:

• an anatomical model module comprising patient-specific data about the geometry of the cochlea of the patient or of a part thereof;
• a cochlea path module comprising patient-specific data about a spiral path of the cochlea of the patient or of a part thereof;
• a cochlea area module comprising empirical data about cross-sectional areas of a human cochlea or of a part thereof perpendicular to a corresponding spiral path of the human cochlea for different insertion angles;
• an electrode array geometry module configured to compute a predicted arrangement of the electrode array when received within the cochlea of the patient based on the patient-specific data about the geometry of the cochlea of the patient or of said part thereof and on a predefined geometric relation between the geometry of the cochlea of the patient and the predicted arrangement of the electrode array within the cochlea of the patient;
• and
• an electrode array design module configured to determine the target geometry of the electrode array corresponding to the predicted arrangement of the electrode array within the cochlea of the patient computed by the electrode array geometry module,
• wherein the anatomical model module is configured to generate the patient-specific data about the geometry of the cochlea as volumetric data based on the patient-specific data about said spiral path and on the empirical data about said cross-sectional areas.
