Presentation and physical evaluation of RadioVisioGraphy.
A comparison of physical properties has been made between conventional intraoral films and images made with the RadioVisioGraphy (RVG) system, a unit based on the charged coupled device. The RVG system uses considerably reduced levels of radiation to produce an image immediately after exposure. RVG resolution is slightly lower than that with silver halide emulsion films; however, radiographic information may be increased by electronic image treatment.
