Although X-rays have existed since the early 1900s, digital radiography has not existed since 1970. However, since then, digital radiography has been implemented in more and more hospitals, imaging centers and larger and smaller medical facilities. fields of specialization. Commonly used imaging systems include CR and DR systems.
Digital radiography, or computerized radiography, uses a phosphor imaging cassette to create digital images, while digital radiography systems, or digital direct radiography, use a collection plate for image capture. . R & D systems are currently used as emergency care units, veterinarians, chiropractors and chiropodists. These two systems, along with associated hardware and software units such as the DICOM digital format, PACS and RIS, have allowed many medical facilities to modernize in the modern era with state-of-the-art digital radiography capabilities. of technology.
Many of the first inventions and applications of medical digital radiography occurred at about the same time that personal computers became more affordable and therefore more commonplace. The first digital imaging application was the invention of the scanner or CT scanner in 1967, which became a prototype in 1971. Its inventors, Godfrey Hounsfield and Allan McLeod Cormack, were awarded the Nobel Prize for Medicine for their invention in 1979. Television technology has also paralleled medical technology innovation with the shift from analog to digital capabilities.
MRI, or magnetic resonance imaging, was born in the 1950s. The first research on this method was conducted in the 1970s and was finally authorized for use on humans in 1984 .
In the 1990s, digital radiography evolved. X-ray images, it was discovered, could be stored on phosphor screens, which formed the basis of current CR imaging systems.
Complementary PACS systems debuted in 1982, although the idea was designed more than twenty years earlier. When the Internet became a global reality in the mid-1980s, it also had a major impact on digital radiography. Digital medical images recorded in DICOM format, similar to the current JPEG format, can be stored on a server for archival purposes, viewed on a computer equipped with PACS software and a diagnostic monitor transforming it into a computer. a clinical workstation, and can be sent and received via the World Wide Web.
Over the last decade, the price of personal computers and other electronic devices has dropped dramatically, as has the profitability of digital medical imaging, making digital radiography an affordable and modern alternative to its humble beginnings in the field of digital imaging.
