What is basic principle of x-ray?
CT, radiography, and fluoroscopy all work on the same basic principle: an X-ray beam is passed through the body where a portion of the X-rays are either absorbed or scattered by the internal structures, and the remaining X-ray pattern is transmitted to a detector (e.g., film or a computer screen) for recording or …
What is the principle used to produce monoenergetic X-rays?
Monoenergetic x-rays produced by the ejection of a K-shell electron from an element (e.g., the target of an x-ray tube) and the subsequent filling of the vacant electron by electrons from shells with lower binding energies, with energy equal to the difference in the binding energies of the shells.
What are the steps in x-ray production?
There are four essential requirements for the production of x-rays: (1) a vacuum, (2) a source of electrons, (3) a target, and (4) a high potential difference (voltage) between the electron source and the target.
What are the four primary factors of x-ray production?
The quantity and quality of the x-ray beam are controlled by four prime factors. These factors are under the direct control of the limited operator. The prime factors of exposure are milliamperage (mA), exposure time (S), kVp, and SID.
What is Xray production?
X-rays are commonly produced in X-ray tubes by accelerating electrons through a potential difference (a voltage drop) and directing them onto a target material (i.e. tungsten). The X-ray photons produced in this manner range in energy from near zero up to the energy of the electrons.
What are the properties of X-ray?
Properties of X-Rays
- They have a shorter wavelength of the electromagnetic spectrum.
- Requires high voltage to produce X-Rays.
- They are used to capture the human skeleton defects.
- They travel in a straight line and do not carry an electric charge with them.
- They are capable of travelling in a vacuum.
What is the basic inner process of x-ray production?
X-rays are produced due to sudden deceleration of fast-moving electrons when they collide and interact with the target anode. In this process of deceleration, more than 99% of the electron energy is converted into heat and less than 1% of energy is converted into x-rays.
What are 6 characteristics of x-rays?
X-rays have waveform characteristics of velocity, wavelength, frequency and amplitude. Many materials are transparent to x-rays, while lead and other dense materials will not transmit the radiation. X-rays can be detected with photographic film, similar to visible light.
What is radiation production?
Ionizing radiation is produced by unstable atoms. Unstable atoms differ from stable atoms because unstable atoms have an excess of energy or mass or both. Radiation can also be produced by high-voltage devices (e.g., x-ray machines). In order to reach stability, these atoms give off, or emit, the excess energy or mass.

What are the 12 properties of X-rays?
What are the disadvantages of an X ray?
x-rays makes our blood cells to have higher level of hydrogen peroxide which could cause cell damage.
What are the advantages and disadvantages of X – rays?
Costs. One advantage of X-rays is that they are cheaper than similar medical procedures.
What is the purpose of X ray film?
X-ray film – photographic film used to make X-ray pictures bitewing – a dental X-ray film that can be held in place by the teeth during radiography photographic film, film – photographic material consisting of a base of celluloid covered with a photographic emulsion; used to make negatives or transparencies
What are the uses of X – ray?
Uses of X-rays X-rays can be used to treat tumors in the human body. Because of X-rays, doctors are able to easily detect things such as a bone fracture or sprain in the body. X-rays are not only used in the destruction of malignant tumors, but they are also used by doctors to treat leukemia.
