The latest version of the Radiovisiography-system was evaluated in comparison to its predecessor and a high speed periapical film (Agfa Dentus M4). Both RVG-systems proved to have the same sensitivity and are capable of displaying a similar contrast range. Nevertheless additional functions of the new system allow a much better visualisation of the radiographed structure. Compared with Dentus M4 periapical films the RVG-System provides less sensitivity but a wider range of contrast.
对最新版本的放射成像系统与其前身以及高速根尖片（爱克发 Dentus M4）进行了评估比较。两种放射成像系统的灵敏度相同，且都能够显示相似的对比度范围。然而，新系统的附加功能使所拍摄结构的可视化效果更好。与 Dentus M4 根尖片相比，放射成像系统的灵敏度较低，但对比度范围更广。
