Doses for facial trauma patients on conventional CT scanners and the new dental cone-beam CT scanners

CT is currently the imaging method of choice for the diagnosis of fracture of the lower orbits in facial trauma. However, Dental Cone Beam CT (CBCT) has the potential for higher resolution images with lower doses to the patient. The Charles Clifford Dental Hospital in Sheffield has recently installed an i-CAT CBCT unit and we are embarking on a project looking at its suitability for imaging the lower orbits and whether there are potential dose savings, particularly to the lens of the eye.

The project is still in the very early stages and suggestions would be welcome as to which specific quantities to use as dose comparators, and practical aspects of measuring image quality and dose, including the applicability of CTDI to Cone-Beam CT.
