Radiology: X-ray and Body
Humanity, constantly learning, growing, and facing more challenges each second of the day. Whether the challenges are mental or purely physical, we have found more efficient, safer, and easier ways of doing the tasks we may face. From moving cargo to sending information via the Internet. Probably the greatest accomplishments we have made, are in the studies of medicine/treatment; to be specific, the study of radiology. Radiology is the process of working and viewing inside the human body without breaking the skin. By using radiant energy, which may take the form of x-rays or other types of radiation, we are able to diagnose and treat many diseases and injuries. Both diagnostic and therapeutic radiology involve the use of ionizing radiation (Beta, Alpha, Gamma, and x-rays), with the exception of the MRI, which uses a magnetic field rather than radiation. Radiology is classified as being either diagnostic or therapeutic. Diagnostic radiology is an evaluation of the body, by means of static or dynamic images or anatomy, physiology, and alterations caused by injury or disease. A majority of these pictures are formed by passing a low or high level of x-rays through the part of the body being examined, producing the static image on film. This image is called a radiograph or x-ray picture. The image itself may have many forms. It could be a common radiograph, such as a chest x-ray; a tomography, greek for "section", which is a radiograph obtained by timing the x-ray exposure to correspond with the movement of the x-ray tube and film in opposite directions around the plane of the body; or, finally, a computerized axial tomography (CAT or CT) scan. Which is a computer analysis of a sharply limited, thin x-ray beam passed circumferentially through an area of the body, giving the doctor of Technician a cross-sectional image; much like that of slicing a loaf of bread into sections. Other images may be obtained by using ultrasound or MRI, or by
