9000 3D Extraoral Imaging System Information
Our 9000 3D Extraoral Imaging System generates the highest-resolution images at the lowest dose, and confines the field of view to narrow regions of interest to further limit radiation. Below is our dosimetry chart for common techniques.

9500 Cone Beam 3D System Information
Our 9500 Cone Beam 3D System delivers an optimized dose and is the best unit for many cases, particularly those involving multiple implant sites, cranio-facial trauma, TMJ dysfunction and more. It exposes patients to significantly less radiation than medical-grade CT, which is the only viable alternative in many instances. Below is our dosimetry chart for common techniques.
