1. What is an RVG sensor?
RVG stands for Radio Visio Graphy.
This technology can replace dental X-ray examination.
The sealed sensor housing makes the sensor waterproof and can be used in a variety of applications. The anti-vibration layer protects the sensor from bites and drops. The combination of high-sensitivity scintillator, optical fiber and high-resolution rugged CMOS detector helps the sensor to obtain high-quality images.
2. The working principle of RVG sensor
The sensor has two sides: reactive power and reactive power. The reaction side should be used to capture images. The tissue is exposed to X-ray radiation, and the refracted light is captured by the sensor. Process the image immediately and convert it to digital data using an analog-to-digital converter. These digital data are sent to the computer, where the doctor can immediately view the scan results. The cable attachment is located at the invalid end of the sensor.
When the non-reactive surface is exposed to X-rays, no image will appear on the screen. To transfer images to a computer, the sensor has a USB. The USB should be connected to the back of the PC.
The operating voltage of the X-ray generator used should be between 60kV and 70kV. The sensor is not compatible with generators with a voltage lower than 60kV. If the image looks too dark, reduce the exposure time, or if the image looks rough, increase the exposure time. The type of X-ray generator used also affects the image quality.
3. the advantages of RVG sensor
When used in dental imaging, this sensor can reduce the X-ray exposure time. Compared with X-ray radiology methods, the RVG sensor can reduce the patient's X-ray radiation by 80%.
Using this sensor can help doctors get immediate results and reduce patient waiting time. The sensor also provides the flexibility to save the image and change its size or contrast to provide better viewing.
4. the application field of RVG sensor
This sensor is widely used in digital imaging in the dental field. This sensor is also called an intraoral sensor. For different types of applications, RVG offers three sizes-size 0, size 1 and size 2. The size 0 sensor is specially designed for pediatric examinations. Size 1 is a general-purpose sensor and is very useful for vertical images. In order to obtain oblique images and root tips, sensor 2 is used. The use of RVG technology can improve the efficiency of dental X-ray photography.
