Digital X-Ray sensors are the quickest way to acquire x-ray images while offering the benefits of a filmless radiographic system. You simply position the sensor in the mouth, fire the x-ray (at greatly reduced radiation), and the x-ray instantly appears on your computer monitor. You can then view and enhance the x-ray for your diagnostics. It has been shown to increase case acceptance while ...
