  5. the picture, you can see the technologist handling the x-ray tube. She is manipulating the field size by adjusting a device called the collimator which is attached to the x-ray tube housing. The rectangular looking device just above the collimator is the housing for the x-ray tube. The diagram on the right shows the x-ray tube by itself

Components of an X-ray tube. X-ray are only present when power is applied to the x-ray tube. Common metals used as the target in the anode include W, Cu, Mo. Tungsten is also used in the cathode filament. The mechanisms by which the kinetic energy of the electron is converted to x-ray radiation are called Bremsstrahlung and Characteristic x-rays An X-ray tube is generally cylindrically in shape and measuring only 12-18 cm in length and 9 cm in breadth. The envelope is of Pyrex or borosilicate glass tube enables it to withstand extremely high temperature. X-ray tube is housed in a metal housing which is lined with lead except at window. (Th General Tube Construction Housing. The general construction of the tube head assembly is discussed first. Recall that the x-ray tube is situated in a protective housing that provides solid, stable mechanical support. This housing is a lead-lined metal structure that also serves as an electrical insulator and thermal cushion for the tube itself (Figure 5-2) The production of X-rays for diagnostic imaging requires fast moving electrons to be rapidly decelerated; the design and function of the major components to facilitate this will be discussed. The key components of a modern rotating anode X-ray tube (Fig. 8.1) are: • Tube housing. • Vacuum envelope. • Filament assembly

  3. History. X-ray tubes evolved from experimental Crookes tubes with which X-rays were first discovered on November 8, 1895, by the German physicist Wilhelm Conrad Röntgen.These first generation cold cathode or Crookes X-ray tubes were used until the 1920s.The Crookes tube was improved by William Coolidge in 1913. The Coolidge tube, also called hot cathode tube, is the most widely used
  4. X-Ray Generators. Half wave rectification -The negative part of the sine wave is simply chopped off. A generator that produces this type of waveform is called a . single phase, half wave rectified generator. -This type of generator produces 60 pulses of x-rays a second -X-rays are produced in spurts, like taking a picture with a strobe light

and the combination can result in a high demand on the X-ray tube. Special X-ray tubes are generally found in such systems. Focal spot sizes in fluoroscopic tubes can be as small as 0.3 mm (when high spatial resolution is required but low radiation output can be tolerated) and as large as 1.0 or 1.2 mm when higher power is needed 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. X-rav tube: - There are two main kinds of x-ray tubes - the stationary anode and the rotating anode tube. The later one is preferred for the simulator because it is able to with stand more power without being damaged. An x-ray tube is made up of a cathode and an anode. Cathode: - The cathode assembly contains a filament, which is a coil of. X-ray Spectrum X-ray spectrum of Mo at different voltage X-rays are produced when accelerated electrons collide with the target. The loss of energy of the electrons due to impact is manifested as x-rays. X-ray radiation is produced in an x-ray tube. Most of the kinetic energy of the electrons striking the target is converted into heat, less than 1

Rotating envelope x-ray tubes (RET), are a relatively novel type of high-performance x-ray tube developed in the early 2000s.

Radiation produced from x-ray photons or electrons that have reflected off the anode These x-rays or electrons can strike a number of things in the tube and produce scatter photons: Because they are not produced in the focal track they are off-focus and while most are absorbed by the housing, some make it out of the tube and degrade the. energy of the x-ray.

Responsibilities of Employer, Licensee, RSO and Radiation Worker 7 X-ray units that are currently manufactured cover both the superficial and orthovoltage regions and even the contact regions. For example, Gulmay Medical Ltd. offer a superficial model, 2000, with x-ray energies from 10 to 150 kV and two other models, 3225 and 3300, with x-ray energies between 25 and 220 kV and 40 and 300 kV respectively The energy of an x-ray beam may be described by identifying the peak operating voltage (in kVp). A dental x-ray machine operating at a peak voltage of 70,000 volts (70 kVp) for example, apples to a fluctuating voltage of as much as 70 kVp across the tube. This tube therefore produces x-ray photons with energies ranging to a maximum of 70,000 ke The Protective Housing guards against excessive radiation exposure and electrical shock. When x-rays are produced, they are emitted isotopically, that is with equal intensity in all directions. We use only those emitted though the special section of the x-ray tube called the window. Those x-rays emitted through the window are called the useful. The X-ray spectrum. As a result of characteristic and bremsstrahlung radiation generation a spectrum of X-ray energy is produced within the X-ray beam. This spectrum can be manipulated by changing the X-ray tube current or voltage settings, or by adding filters to select out low energy X-rays

The idea behind ultrafast CT is a large, bell-shaped x-ray tube (supplemental Fig. 13) . An electron. X-ray production is directly proportional to the tube current; thus, doubling the tube current doubles the number of x-rays produced at a particular kVp. X-ray production increases more rapidly with kVp than mA, and increasing the kVp by 15% is equivalent to doubling the mA. Higher kVp values also provide a more penetrating x-ray beam
