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. FIG. 5-3 Simple x-ray tube. The anode is the positive end of the tube; the target is part of the anode X-Ray Production •Radiation-producing devices produce X-rays by accelerating electrons through an electrical voltage potential and stopping them in a target. •Many devices that use a high voltage and a source of electrons produce X-rays as an unwanted byproduct of device operation X-ray production at the anode. The electrons hit the anode with a maximum kinetic energy of the kVp and interact with the anode by losing energy via: Elastic interaction: rare, only happens if kVp < 10 eV. Electrons interact but conserve all their energy; Summary of steps

Four conditions are necessary for the production of diagnostic X-rays: 1 A source of free electrons. 2 A means to provide the electrons with high kinetic (motion) energy. 3 A method to concentrate the electrons into a beam Pushing the exposure button activates the high-voltage circuit, electrons in the cloud are shot across the x-ray tube to the anode Step 4 The electrons speed from the cathode to the anode, 1% of energy is converted to x-ray, 99% loss is hea

X-ray production. Dr Daniel J Bell and Dr Prashant Mudgal et al. 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 The X-ray tube A small increase in the filament voltage (1) results in a large increase in tube current (2), which accelerates high speed electrons from the very high temperature filament negative cathode (3) within a vacuum, towards a positive tungsten target anode (4). This anode rotates to dissipate heat generated 5.2 Fundamentals of X Ray Production 5.3 X Ray Tubes 5.4 Energizing & Controlling the X Ray Tube 5.5 X Ray Tube & Generator Ratings 5.6 Collimation & Filtration 5.7 Factors Influencing X Ray Spectra & Output 5.8 Filtration Bibliography Diagnostic Radiology Physics: a Handbook for Teachers and Students -chapter 5, 2.

29. Factors Affecting X-ray Production • The output of an x-ray tube is often described by the terms: - Quality : the penetrability of an x-ray beam - Quantity : the number of photons comprising the beam - Efficiency : the ratio of output energy as x-rays to input energy deposited by electrons 29. 30 4 4 The X-ray film is a delicate product, sensitive to many things, e.g. light photons, X-rays and gamma rays, pressure, to various gases and fumes, to heat and moisture and even aging causes a gradual change in it; known as fogging. PROCESSING CHEMICALS. A. DEVELOPER (Reducing Agent) Chemical Actio X-Ray photons are electromagnetic radiation with wavelengths typically in the range 0.1 - 100 Å.

There are three common mechanisms for the production of X-rays: the acceleration of a charged particle, atomic transitions between discrete energy levels, and the radioactive decay of some atomic nuclei. Each mechanism leads to a characteristic spectrum of X-ray radiation Within the x-ray circuit, the electrical device that operates on the principle of mutual induction and serves to increase voltage and decrease current is known as the A rectifier B step-up transforme Any X-ray apparatus, even of the simplest type, is an intricate and complicated piece of machinery consisting of four main parts: The X-ray tube, the transformer, the tube stand, and the control panel. 1 Since x-ray photons are very energetic, they have relatively short wavelengths. For example, the 54.4-keV K α x ray of Example 1 has a wavelength [latex]\lambda=\frac{hc}{E}=0.0228\text{ nm}\\[/latex]. Thus, typical x-ray photons act like rays when they encounter macroscopic objects, like teeth, and produce sharp shadows; however, since atoms. An x-ray tube functions as a specific energy converter, receiving electrical energy and converting it into two other forms of energy: x-radiation (1%) and heat (99%). Heat is considered the undesirable product of this conversion process; therefore x-radiation is created by taking the energy from the electrons and converting it into photons.This very specific energy conversion takes place in.

3.0 Production of X -rays Cross section of sealed-off filament X-ray tube target X-rays tungsten filament Vacuum X-rays are produced whenever high-speed electrons collide with a metal target. A source of electrons- hot W filament, a high accelerating voltage between the cathode (W) and the anode and a metal target, Cu, Al, Mo, Mg X-rays are generated in a cathode ray tube by heating a filament to produce electrons, accelerating the electrons toward a target by applying a voltage, and bombarding the target material with electrons. When electrons have sufficient energy to dislodge inner shell electrons of the target material, characteristic X-ray spectra are produced The X-rays pass through the body, creating an image on film or a computer display. The equipment, staff, and steps involved are different for each type of diagnostic X-ray procedure. However, they are all invaluable tools in detecting abnormalities and making early diagnosis of disease or injury * Technical factors of x-ray production: kVp, mAs, exposure time, and distance. Below: An x-ray of an aluminum step wedge is shown. Step wedges demonstrate that the thicker the body part, the less x-rays are able to penetrate through. It also shows how the amount of contrast changes according to the kVp selected Hand-held x-ray equipment must incorporate into its design physical means to protect the operator from leakage radiation with sufficient shielding surrounding the source assembly to ensure.

Routine X-rays are considered fairly safe but most doctors recommend waiting at least 6 months and sometimes up to a year to undergo the same routine X-ray due to radiation exposure, unless they are needed sooner (as often you may need a repeat CXR 1-2 weeks after pneumonia, or repeat films in a few weeks for fractures) X-rays produced by Bremsstrahlung are the most useful for medical and industrial applications. After interacting with the atom, the free electron loses energy in the form of an X-ray photon What is bremsstrahlung? Bremsstrahlung is a German term that means braking rays. It is an important phenomenon in the generation of X-rays The reproducibility of timer accuracy and mA calibration tests are important parameters to ascertain X-ray production quality. Using a digital X-ray exposure timer (RMI, model 221A), we tested the timer accuracies of X-ray exposures. The source-to-detector distance was set at 100 cm for the three-phase units and 75 cm for the single-phase unit 4-1 X-ray daily log sheet.. 4-2. vii. 1-1 1.

The production of film density and the formation of a visible image is a two step process. The first step in this photographic process is the exposure of the film to light, which forms an invisible latent image. The second step is the chemical process that converts the latent image into a visible image with a range of densities, or shades of gray Pair production (PP) can occur when the x-ray photon energy is greater than 1.02 MeV, but really only becomes significant at energies around 10 MeV. Pair production occurs when an electron and positron are created with the annihilation of the x-ray photon. Positrons are very short lived and disappear (positron annihilation) with the formation. The voltage applied across the X-ray generator at the time of X-ray production is known as the kV. Increasing the kV results in increased energy of the X-rays produced and, therefore, the ability of the X-ray beam to penetrate the patient's tissues also increases.

QC of general X-Ray machine. 2. X-RAY PRODUCTION 2. 1. PRODUCTION OF X-RAY X-Rays for medical diagnostic procedures or for research purposes are produced in a standard way: by accelerating electrons with a high voltage and allowing them to collide with a metal target. X-Rays are produced when the electrons are suddenly decelerated upo In order to evaluate the problem of x-ray tube heating, it is necessary to understand the relationship of three physical quantities: (1) heat, (2) temperature, and (3) heat capacity. Heat is a form of energy and can be expressed in any energy units. In x-ray equipment, heat is usually expressed in joules (watt-seconds) or heat units X-ray production typically involves bombarding a metal target in an x-ray tube with high speed electrons which have been accelerated by tens to hundreds of kilovolts of potential. The bombarding electrons can eject electrons from the inner shells of the atoms of the metal target. Those vacancies will be quickly filled by electrons dropping down.

X-Ray Generation Note

rays were called X-rays. Roentgen showed that X-rays are a form of electromagnetic energy and are part of the same spectrum as light (Figure 5-1). They travel at the same velocity of light and obey most of its laws though their wavelength is very much shorter. It is this shorter wavelength that allows X-rays to penetrate materials 1. X-ray tube: An envelope of glass containing a filament, target, and an extremely high vacuum. High melting point—in order to withstand higher temperatures—hence a higher capacity in production of xrays. High atomic weight—to secure a better output of radiation, or characteristic x-rays of a better quality Some people who suffer from immense osteoarthritis knee pain may only show mild changes on x-ray, so it is extremely important to concentrate on the symptoms, rather than just the x-rays. Here is a look at the stages of osteoarthritis of the knee ranging from normal, minor, mild, moderate and severe stages, with appropriate treatment plans

Radiation therapy. X-rays play an important role in the fight against cancer, with high energy radiation used to kill cancer cells and shrink tumours. Patients undergo treatment outside the body (known as external-beam radiation therapy) or from radioactive material that's inserted into the body in close proximity to cancer cells Increasing the x-ray tube voltage will generate (many) more x-rays, as shown in Figure 2, but will also increase the beam energy (quality/HVL). In radiography, the x-ray tube output (air kerma) is generally taken to be proportional to kilovoltage squared, whereas in CT the x-ray tube output is taken to be proportional to kilovoltage to the 2. The chest x-ray is the most commonly performed diagnostic x-ray examination. A chest x-ray produces images of the heart, lungs, airways, blood vessels and the bones of the spine and chest. An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part. Step 4: Identify Production Bottlenecks. Production bottlenecks occur when there is a breakdown somewhere on your production line. People often assume machine- or equipment-related deficiencies drive bottlenecks. However, organizations have the most costly bottlenecks in the human components of their processes X-ray - X-ray - Fundamental characteristics: X-rays are a form of electromagnetic radiation; their basic physical properties are identical to those of the more familiar components of the electromagnetic spectrum—visible light, infrared radiation, and ultraviolet radiation. As with other forms of electromagnetic radiation, X-rays can be described as coupled waves of electric and magnetic.
