Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to compare the irradiation between Cone Beam and CT of the petrous bone.

The primary endpoint is the measurement of equivalent doses per organ of interest (eyes, ears, thyroid and external genitalia).

The investigators have set up a prospective monocentric study. The investigators will measure irradiation of these different organs using nanodots placed on the patient during imaging.

The results of these measurements will be compared between Cone Beam (performed in the Besançon University Hospital ENT department for cochlear implant position checks) and CT (all indications combined).
