X-rays, CT scans and other diagnostic imaging procedures—all radiology techniques—are used to help locate, stage and diagnose cancers. Radiation therapy is a treatment that uses high doses of targeted energy to kill cancer cells and shrink tumors. Advertising on our site helps support our mission.

X rays are electromagnetic radiation that differentially penetrates structures within the body and creates images of these structures on photographic film or a fluorescent screen. These images are called diagnostic x rays.

Even those the X-Rays are specifically focused on a single target, the x-rays will still scatter and those scattered rays can continue to scatter around the room based on various design features. Scatter radiation. The bulk of this type of radiation derives from the X-rays bouncing off the patient's body.

Visible light and X-Rays exist on the same spectrum of waves. They are both electromagnetic waves. The difference between the two is that the human eye can only see light between about 400–700 nm wavelength. X-Rays typically have a wavelength of about 0.01–10 nm.

Radiology is a medical specialty that uses imaging to diagnose and treat diseases seen within the body. ... The radiology department may also be called the X-ray or imaging department. It is the facility in the hospital where radiological examinations of patients are carried out, using the range of equipment listed above.

X-rays are produced when the electrons are suddenly decelerated upon collision with the metal target; these x-rays are commonly called brehmsstrahlung or "braking radiation". If the bombarding electrons have sufficient energy, they can knock an electron out of an inner shell of the target metal atoms.

Diploma in X-Ray Technology is a undergraduate radiology course that is an electromagnetic radiation that penetrates within the human body and creates image of those structures on a photographic film. Radiological Technology is the production of medical images commonly called as X-rays.

The difference between the two comes down to definitions of the two words. An x ray is a photon of energy. This is what is exposing the patient for the final image. ... A radiograph is the resultant image after a patient or object is exposed to x rays.

AP, X-ray: An X-ray picture in which the beams pass from front-to-back (anteroposterior). As opposed to a PA (posteroanterior) film in which the rays pass through the body from back-to-front.

Cathode-rays is not electromagnetic in nature. Cathode rays (electron beam or e-beam) are streams of electrons observed in vacuum tubes.

X-rays are a form of electromagnetic radiation that can penetrate clothing, body tissue, and internal organs. An X-ray machine sends this radiation through the body. Some of the radiation emerges on the other side of the body, where it exposes film or is absorbed by a digital detector to create an image.

noun Also x ray, X ray. Often x-rays. a form of electromagnetic radiation, similar to light but of shorter wavelength and capable of penetrating solids and of ionizing gases.

X-rays work just like visible light (in fact they're just a higher energy form of light) in that they are able to pass straight through some materials (just like light passes through glass) but not through others (just like light doesn't get through walls).

X-rays with high photon energies (above 5–10 keV, below 0.2–0.1 nm wavelength) are called hard X-rays, while those with lower energy (and longer wavelength) are called soft X-rays.

X-rays can be generated by an X-ray tube, a vacuum tube that uses a high voltage to accelerate the electrons released by a hot cathode to a high velocity. The high velocity electrons collide with a metal target, the anode, creating the X-rays.
