Abstract
A comparison of the physical properties of a new charge-coupled device-based direct digital intraoral radiographic system, its predecessor, and high-speed silver halide intraoral radiographic films is reported. The new system proved to have a higher dose dynamic than the former device. The resolving power of the new system is 11 line pairs/mm compared with a maximum of 14 line pairs/mm for intraoral film.
摘要
报告了一种新型基于电荷耦合器件的直接数字化口腔内射线照相系统、其前身以及高速卤化银口腔内射线照相胶片的物理特性比较。新系统被证明比前一种设备具有更高的剂量动态范围。新系统的分辨力为11线对/毫米，而口腔内胶片的最大分辨力为14线对/毫米。
