The History Of Radiology-adobe gamma

Reference-and-Education The history of radiology goes back to 1895 when Wilhelm Conrad Rntgen discovered the x-ray, describing the properties of this previously unknown type of electromagnetic radiation in stunning detail. In the early 1900s, people started using x-rays for all sorts of things, even for purposes such as helping to fit shoes! The medical uses of x-rays were the only applications that persisted, though, as the dangers of ionizing radiation were discovered. At first, all sorts of medical and non-medical professionals used x-rays in hospitals and clinics. Everyone from doctors and nurses to engineers and photographers could use x-rays, and they didnt typically have any kind of specialized training. It wasnt long until a professional subset of the medical .munity was built up around the field of radiography, though. Newer and safer diagnostic testing techniques were developed, and specialized training was required to operate the machines used for these tests. Radiographers emerged as a new type of medical professional with the specialized training to adapt to this new technology. New technologies developed in the field of radiology throughout the 1940s, 50s, 60s, 70s and 80s, from fluoroscopy and mammography, to tomography and ultrasound, to nuclear medicine and .puted tomography. Magnetic Resonance Imaging, also known as MRIs, emerged in the 1950salthough extensive research was not done until the 1970s, and the technology wasnt used on humans until 1984. Digital radiography, also known as .puted radiography, did not emerge until the 1970s. This technology uses imaging cassettes of phosphor to create digital images. The invention of the .puted tomography scanner, or CT scan, developed from an early application in 1967 that led to a prototype in 1971 by Allan McLeod Cormack and Godfrey Hounsfield. .puters began playing a much bigger role in the 1980s, when .plementary PACS systems debuted and impacted digital radiography in major ways. Now radiographic images can be stored in the DI. format, which is similar to a JPEG, and can be sent and received via the Internet. The biggest advances in radiology since the 1990s have been in the accessibility, cost and convenience of the technology. The drastic drop in price (and size) of electronic devices and personal .puters has made digital medical imaging much more cost effective, allowing the technology to spread further and impact more lives. As technology continues to advance, who knows what the history of radiology will look like at the beginning of the next century? About the Author: 相关的主题文章:
