Ever since X-rays have got introduced in the medicine sector, these have witnessed a great evolution in the past century.
However, the main principle is same as it was in 1895.
Also dubbed radiographs or roentgenograms for having been introduced by W.
C.
Roentgen, x-rays are radiated using an x-ray source through the part of the body that needs to be examined and onto a film.
The film is exposed by a special phosphor coating which glows inside the film cassette.
The film comes out as a regular photograph.
X-rays have a special energy and wavelength, and these let the radiations penetrate the body organ to form an image of the same.
The internal structures such as bones appear on the x-ray image.
When the radiations pass through the body part, tissues with different density that come across the rays attenuate these.
A great amount of x-rays is either absorbed or attenuated by bones, for these are denser than other organs.
Soft tissues, on the other hand, are less dense and thus, absorb significantly less x-ray energy.
The difference clearly shows on the x-ray image that comes out.
This is the reason why any clogged blood vessels, broken bones, cancerous tissues and any other kinds of abnormalities can be clearly seen on the x-ray images.
Fluoroscopy and its Principles Many of the principles of fluoroscopy are very much similar to radiography or film x-ray principles, which are mentioned afore.
Nevertheless, a moving x-ray image or film is produced by fluoroscopic imaging.
The existing fluoroscopes comprised a fluorescent screen and an x-ray system which stored x-rays and radiated glowing light.
The fluorescent screen could be viewed by doctor who could even get a dynamic image of the body of the patient.
Besides, ever since television cameras have got introduced along with fluoroscopic image intensifiers, fluoroscopic technology has witnessed a great deal of improvement.
Presently, a number of conventional x-ray systems have attained the potential to shift back and fro between the fluoroscopic and radiographic modes.
The modern x-ray machines have even gained the potential to get hold of radiograph or fluoroscopic movie through digital acquisition.
It is thus that the radiologist can better control the image quality as well as interpretation.
Also, they can now ensure minimal radiation doses.
With the help of digital imaging, it is now possible to network the final image to different spots for any further interpretation or consultation.
