1987年，第一个用于口内放射照相的数字传感器RadioVisioGraphy问世。它是基于一个电荷耦合器件（CCD）传感器的活动。后来，其他数字传感器开始商业化，包括1994年的Digora，其特征是涂有光刺激荧光粉（PSP）的成像板，以及1998年的互补金属氧化物半导体传感器，CDR有源像素传感器。这些技术最近经历了相当大的改进，一些牙科诊所已经从基于胶片的系统转向数字成像。在早期，数字传感器在临床诊断中被认为不如胶片，但根据最近的研究结果，由于性能的提高，不再有明显的差异。然而，我们的最新研究使用了一种新的评估方法和精确的幻影模型，表明CCD和PSP系统的性能存在一些差异，并且不同功能和性能的PSP系统之间存在进一步的差异。
The first digital sensor used in intraoral radiography, RadioVisioGraphy was introduced in 1987. It was based on the activity of a charged-Coupled Device (CCD) sensor. Later on, other digital sensors became commercially available, including the Digora featuring an imaging plate coated with photostimulable phosphor (PSP) in 1994 and the complementary metal-oxide semiconductorbased sensor, CDR active pixel sensor, in 1998. These technologies have recently undergone considerable improvement, and several dental clinics have switched from film-based systems to digital imaging. In the early days, digital sensors were considered inferior to film in clinical diagnostics, but according to recent research results, there is no longer any significant difference because of the improvement in performance. However, our latest research using a new evaluation method and a precise phantom model indicated some differences between the performance of CCD and PSP systems and further differences between PSP systems of different function and performance.
