Radiovisionography

Radiovisiographyis a modern method of computer processing of intraoral and extraoral X-ray images. The difference between traditional X-ray and RVG is in the medium that captures X-rays – instead of a film film, a special sensor is inserted into the mouth, which converts the image into digital form, and the X-ray images are thus immediately displayed on the computer monitor.

Advantages

• 50–90% reduction in radiation dose
• the use of X-ray films and chemicals for developing them is eliminated
• the images are immediately available to the doctor, they can be edited and printed
• easy archiving of digital images

Disadvantages

• an x-ray cannot be used in court because it can be post-edited on a computer (not true, digital photos and x-rays are commonly accepted by the court and the forensic expert; if tampering is suspected, changes to the image can be easily proven)^[source?]
• the sensor is inflexible compared to classic film foil; this drawback can be circumvented by using indirect film radiovisiography
