Study Overview
Brief Summary
Cone beam computed tomography (CBCT), is a recent medical imaging technique where the X-rays are divergent, forming a cone.
As a result, this technique is less irradiating that the scanner. The purpose of this exploratory study is to compare the performance of the scanner and the cone beam in the detection of anatomical structures of the ear.
