Characterization of the cadmium telluride photon-counting sensor as applies to its use in the QRMaster-P panoramic machine

Abstract

This study was undertaken to perform in vitro investigations of several potential important clinical applications of a new Cadmium Telluride Photon Counting (CdTe PC) sensor fitted to a newly designed panoramic machine. The study was divided into three parts and each of the three clinical applications was highly relevant to the current clinical practice of dentistry. More importantly, these functions were either not clinically possible with the use of existing panoramic machines or when standard panoramic devices were employed, clinically inaccurate data was obtained from the images. The aims of the three projects were as follows: Project 1. To investigate whether bone mineral density (quality) could be determined more accurately using the QR Master-P test machine than by one representative standard panoramic device and one representative hybrid pan cone beam computed tomography (CBCT) scanner in the standard pan mode; Project 2. To determine whether different restorative materials could be separated from each other and identified using the QR Master-P test device as compared to one standard panoramic machine and one hybrid pan-CBCT device in the standard pan mode and Project 3. To determine whether angular measurements could be made accurately using the QR Master-P test system as compared to a standard panoramic machine.
