There are three basic components of a digital imaging system: computers (desktops, viewing stations), detectors (image acquisition devices) (Figures 2a and 2b), and scanners (Figures 3a and 3b). The steps involved in a digital imaging cycle are illustrated in Figure 1. This article examines each these elements and also identifies concerns that are essential to the clinical practice of dentistry. There are five basic elements of an imaging cycle: acquisition of a digital image processing the acquired image using image analysis, and image manipulations using software applications storage for easy access and retrieval communication or image transmission between peers and presentation or viewing of the image using monitors or workstations. The purpose of this article is to review technologies basic to digital imaging that enable acquisition and viewing of an image, and to recognize limitations of the technology. There is also evidence that utilization of digital radiography is not only more economical to establish than a conventional radiographic system, but also less expensive to maintain. Other advantages include image analysis and image reconstruction. In addition, digital imaging does not require chemical processing. Images produced by digital systems can also be manipulated using computer software applications to increase diagnostic utility and electronically transmitted for referrals. The lower dose of radiation and time saved in acquisition and viewing of an image is an improvement over conventional radiography. Information obtained in digital form can be processed, stored, and transmitted from one place to another using communication networks. 1ĭigital imaging offers several advantages. In a survey conducted in 1998, 67% of the dentists responding to the question of their next major purchase wish, if “money was no object,” said that they would buy a digital radiography system. Estimates by manufacturers place the number of dentists who have purchased these systems to be approximately 7,000. However, dentists in North America have been slow to adopt digital radiography. Digital imaging has been used in the practice of dentistry since the 1980s to diagnose diseases of the paranasal sinus and TMJ disorders. Digital radiography refers to all non-film-based methodologies to capture radiological information.
