How to Open rvg Files?

To open rvg files, you need a special intraoral driver installed in the system. From any tool supporting the sensor x-ray imaging, one can open the x-ray image file and then can be exported as image files.

Radio Visio Graphy (RVG) are generated from the 3-dimension image creation software attached to sensor devices you will find in digital dental clinics. Dental x-rays can now be extracted via digital RVG sensors and you eliminate the steps of manual extraction dental x-ray.

Here is the illustration of dental x-ray process shown for RVG vs. conventional method.

The dental sensor device hardware has a USB connection to your desktop/laptop and the x-ray images are rendered via the rvg reader software to view intraoral images on your machine. 

Not every patient or consumer has the rvg reader in their machine (PC/Laptop). For them, the file needs to be converted in JPEG format to view as an image. There are various software in which the RVG captured file is opened and converted into JPEG.

Tips

  • It is always recommended to capture the file in JPEG or PNG while sharing with patients. Patients may not have digital imaging software to view the file.
  • If the RVG file cannot be converted in the image file format from the tool you are using, please capture the file with screen capture and share it.
  • All of the above options to open the dental x-ray (rvg) files are available when you have the tool that renders and reads RVG file(s) via intraoral sensor device.
  • DICOM and Revit External Group File are the driver software that are used to open rvg file(s).
  • No tools available above will work if the RVG file is damaged or corrupted or partially transferred. 
  • You can try changing the file format from RVG and to other format(s) and try opening in the image viewer software such as Paint, PhotoShop or any other preview apps. (This option is not recommended.)
  • Kodak Digital Image Software is another tool that you can use to open the rvg file.
