Ryde X Ray

Early X-rays worked on a simple principle- a suitably sensitive plate was exposed to X-rays, and any solid object that blocked the X-rays appeared as an image on the plate. When providing images of bones this exposed the patient to considerable radiation; suitable photographic plates were not sensitive and exposure times were quite long.


The invention of the vacuum tube (valve) in the 20th century saw the development of the image intensifier. This allowed bright images or X-ray to be visible under normal lighting conditions, while still using lower levels of X-ray radiation. Initial devices appearing in the 1948 used mirrors and optical systems to display the image. Later machines from the 1960s used television technology and photographic film to capture fairly good quality images.


The use of television technology meant that X-rays could be used for surgery, providing real time images.


Digital Radiography

In the late 1980s a French company Trophy radiology produced the first intraoral X-ray imaging system for human diagnostics, though there appears to have been military testing of something using a similar concept on naval planes in the early 1960s. This newer digital system used X-ray sensors rather than older photographic plates or intensified images on television screens. Digital systems can be thought of as a very fine grid, with any square of that grid being either on or off. Direct detection X-ray systems use a flat panel detector. This flat panel produces a digital image corresponding to which parts of the panels are exposed to x-rays.


There are many advantages to digital X-rays. Most notably, the process uses less radiation than ever, and the resulting images (being digital) are easily sent to consulting physicians using the internet.
