You benefit from a reduction in the number of exposure-related retakes, and your patients benefit from the reduction in radiation.

The unique, ergonomic shape of the DEXIS Platinum sensor fits more comfortably against the anatomy and can be moved around the mouth more efficiently even in tough areas. That means you are able to get more clinically useable, more consistent images at a wider range of exposure settings. A double blind, randomized, controlled trial involving DEXIS Platinum and another sensor showed that 88 of the participants found DEXIS to be the most comfortable sensor. Through a combination of advanced hardware and software technologies, the DEXIS Platinum sensor is able to deliver clinically meaningful images that are extremely clear and highly detailed.įancy words, simple concept: DEXIS hardware and software work in harmony to compensate for radiation variances thus guarding against under and over exposure. The ability to see subtleties in X-ray images is crucial to diagnosis, collaboration, and patient communication. All rights reserved.The Platinum sensor lies at the heart of the DEXIS system. The contrast transfer function assessment used in the study confirmed that the spatial frequency at 10% contrast was much lower than the theoretical resolution computed from the pixel size.Ĭopyright © 2013 Elsevier Inc. The Sirona Fullsize charge-coupled device (CCD) Sensor exhibited 10% contrast at 10.3 LP/mm. The Sirona Xios+ Sensor reached a calculated 10% contrast at 13.9 LP/mm. The 10% contrast was found at 18.8 LP/mm for the Duerr VistaRay 7. The Duerr VistaRay 6 Sensor reached a 10% contrast at 9.9 LP/mm. The Dexis Platinum Sensor reached a calculated 10% contrast at 29.52 LP/mm. Image data were analyzed using ImageJ and MatLab to calculate different contrast curves using logistic regression. Stripe patterns with defined amounts of line pairs per mm (2.5-20 LP/mm) were recorded using five commercial digital sensors. Clinicians can move about the mouth efficiently which can mean a more accurate procedure and less retakes due to patient movement.

The aim of this article is to compare the contrast and resolution properties of five different sensors using a known technical target. The unique, ergonomic shape of the DEXIS Platinum sensor fits more comfortably in patients’ mouths and against the anatomy.
