Cochlear Implants: Three-dimensional Localization by Means of Coregistration of CT and Conventional Radiographs

This is the authors' abstract. We don't add key points for this paper.

With use of radiopaque implanted objects as internal fiducial markers, the authors developed and evaluated a technique for coregistering computed tomographic (CT) and computed radiographic images to help determine three-dimensional location information for implant electrodes in the cochlea in phantoms and patients. Three-dimensional positional data from CT were assigned on a radiograph, which permitted identification of individual cochlear electrode locations that were not depicted at CT.
