Title: METHODS AND SYSTEMS FOR OPTIMIZING SELECTION AND PLACEMENT OF COCHLEAR IMPLANT ELECTRODE ARRAYS USING PATIENT-SPECIFIC COCHLEAR INFORMATION AND APPLICATIONS OF SAME
Abstract:
A method for using information of patient-specific cochlea size and/or shape to determine a patient-customized cochlear implant electrode insertion and placement plan includes segmenting shapes of structures of interest (SOIs) of the cochlea in a pre-operative CT image of the cochlea using a shape model; defining a 3D modiolar hugging curve within the shape model of the SOIs as a sequence of points; automatically transforming the defined 3D modiolar hugging curve to the pre- operative CT image so as to obtain a modiolar curve in the cochlea; rigidly registering an EA shape model of the EA to the modiolar curve in the cochlea, thereby placing a resting state shape of the EA within the patient's SOIs such that the EA matches the modiolar curve in the cochlea; and determining a patient-customized insertion plan for electrode placement using the registered EA shape model.
