As use of digital radiography becomes more common, many dentists are wondering if and how they can replace conventional film-based imaging with a digital system. This article briefly describes the different technologies used for digital radiography in dentistry. The article provides general practitioners with a broad overview of the benefits and limitations of digital radiography to help them understand the role the technology can play in their practices.
The two technologies now available are solid-state systems and phosphor plate systems. Each has its strong points, and the choice of which to use depends on the type of dental practice. Image processing improves the diagnostic quality of the radiographic information. Advanced image-processing techniques, such as subtraction radiography, are available for specialized clinics.
Digital radiography no longer is an experimental modality. It is a reliable and versatile technology that expands the diagnostic and image-sharing possibilities of radiography in dentistry. Optimization of brightness and contrast, task-specific image processing and sensor-independent archiving are important advantages that digital radiography has over conventional film-based imaging.
随着数字放射成像的使用越来越普遍，许多牙医都在思考他们是否能够以及如何用数字系统取代传统的基于胶片的成像方式。本文简要介绍了牙科数字放射成像所使用的不同技术。本文为全科医生提供了关于数字放射成像的益处和局限性的广泛概述，以帮助他们了解该技术在其临床实践中所能发挥的作用。
目前可用的两种技术是固态系统和磷光板系统。每种技术都有其优点，具体使用哪种技术取决于牙科诊所的类型。图像处理提高了放射影像信息的诊断质量。先进的图像处理技术，如减影放射成像，可供专科诊所使用。
数字放射成像不再是一种试验性的方式。它是一项可靠且用途广泛的技术，扩展了牙科放射成像的诊断和图像共享可能性。与传统的基于胶片的成像相比，优化亮度和对比度、特定任务的图像处理以及与传感器无关的存档是数字放射成像的重要优势。
