Introduction Visualisation facilitates treatment and understanding. Understanding facilitates rational clinical decisions, patient understanding, acceptance.and informed consent. With the advantage of relatively low radiation compared to conventional cat scans ( from 6 - 35 times less radiation than full scale hospital cat scans). Distortion free images, allowing real measurements in three dimensions. No superimposition of structures. Allows investigate the related hard tissues, airway spaces and their relationship to vital structures such as the inferior nerve bundle in the mandible ( lower jaw) Documentation, legal records, communication with colleagues and patients Saturday 13 April 13
