Digital radiography in dentistry was introduced by the French dentist, Dr. Francis Moyen in the year 1987. The dentist from Toulouse, patented this new technology and called it RadioVisioGraphy (RVG) and developed a prototype. This first sensor was based on the principle of Charged Couple Device (CCD). However, the first version was not computer linked, and the images could be seen on a video screen but could not be saved on a computer. In 1992, Gendex introduced Visualix, the world’s first computer linked digital radiography system. This made storage of images, conversion into various formats and also post-processing possible.
