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 an image file.

Radio Visio Graphy (RVG) is 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 of dental x-ray.

Here is the illustration of the dental x-ray process shown for RVG vs. the 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 into JPEG format to view as an image. There is various software in which the RVG captured file is opened and converted into JPEG.

This is a patient software where one can import an intraoral sensor (RVG) file and view the same or while the sensor is connected the same can be viewed live. 

  1. Open the tool.
  2. Search for the patient for which rvg file is generated or to be generated.
  3. From the left pane, see 2 options:  
    • IO Sensor: If the sensor device is connected, you will see the x-ray image rendered and viewed
    • File Import: If the rvg file is already available, use this option

  • It is always recommended to capture the file in JPEG or PNG while sharing it with patients. Patients may not have digital imaging software to view the file.
  • If the RVG file cannot be converted into 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 an intraoral sensor device.
  • DICOM and Revit External Group File are the driver software that is 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 to another 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.
