This kind of projection radiography is still in use even now

Radiology is that line of medical specialty which focuses on studying, diagnosing and treating ailments inside the human body through the use of imaging. Because technology has met rapid evolvement, there are a number of different techniques that radiologists now apply to get useful images of the inside of the human body.

Radiology is a valuable branch of medical science which lets the radiologists/doctors to better assess what ailment is troubling the patient. oral radiologist  It lets the medical experts have a look inside the patient's body without having to cut it open first. Through visualizing the insides of the body onto a computer screen or an x-ray sheet, the radiologist will know for certain what kind of sickness is affecting which organ precisely.

There is a whole bunch of imaging technologies that a certified radiologist can use to his advantage. When radiology was first introduced a long time ago, there were only x-rays and even that made a breakthrough in the medical science at the time; but for 50 years, oral radiologist  doctors only utilized plain radiography or a chemically developed image on dark film which was enabled when a beam of x-rays are passed through a particular area of the patient. This kind of projection radiography is still in use even now, as it is more cost effective and more widely available. Moreover, this kind of imagery is more suited for the study of the skeleton, heart and bones.

As the branch of radiology expanded, maxillofacial radiology so did the means of catching images from within the body. After the normal x-rays which were captured onto a film, computer topography was introduced; this meant that now the images could be transformed digitally and transferred to a computer. So the radiologist could not directly see the images onto the computer screen.

A more advanced form of diagnostic x-ray imagery is Fluoroscopy which incorporates the use of radio contrast agents, image intensifier tube and a fluorescent screen. It is also used for angiography. The image intensifier tube is attached to the computer system through a closed circuit. The radio-contrast agents have the ability to absorb x-rays and to scatter them; therefore these agents are either injected into the patient or given orally so that they reach the insides of the body maxillofacial radiology. Once the x-rays are shot, a clear real-time image is returned to the television because of the radio-contrast agents. Radiologists use this method when they want to study the blood flow in the veins and arteries or when they want to have a look at the GI tract or genitourinary system.
