A study of scattered radiation in cephalometric radiography

Abstract

Scientific approach to the critical observation of the craniofacial pattern through cephalometry has become increasingly important in medicine and dentistry. Owing to the complexity and increased utilization of cephalometric radiography, the measurement and prediction of scattered radiation dose to occupational personnel working in the radiologic facility is particularly important. This project developed an analysis of the scattering of x-ray photons upon their interactions with an acrylic head phantom using a solid state detector. It was found out that none of the scattered dose measurements exceeded the recommended occupational exposure safety limit by the International Commission on Radiological Protection (ICRP).
