1. A method for automatic segmentation of intra-cochlear anatomy of a patient having an implanted ear and a normal contralateral ear, comprising: obtaining at least one computed tomography (CT) image to generate a first image corresponding to the normal contralateral ear and a second image corresponding to the implanted ear; segmenting intra-cochlear surfaces of at least one first structure of interest (SOI) of the normal contralateral ear in the first image using at least one active shape model (ASM); and projecting the segmented intra-cochlear surfaces in the first image to the second image using a transformation function, thereby obtaining projected segmented intra-cochlear surfaces for the implanted ear in the second image.
