Dental x ray tube head parts and functions

The lead radiation shield protects and supports the anode. - Tube head and cylinder short cone.

The standard structural parts of the dental x-ray machine include a control panel usually mounted behind a protective shield.

Dental x ray tube head parts and functions. This video will help you in understanding the different parts in an x-ray tube head and its functions. A large mass of copper just outside the x-ray tube connected to the anode terminal. It functions to carry off the excess heat produced in the energy exchange that takes place when the electrons of the cathode stream are converted into about 1 x-rays 99 heat.

Conducts the heat away from the target and cools the tube. PARTS AND COMPONENTS OF THE DENTAL X-RAY MACHINE. The standard structural parts of the dental x-ray machine include a control panel usually mounted behind a protective shield.

A tube head which houses the dental x-ray tube. And a flexible extension arm from which the tube head is suspended see figure 1-1. When a beam of x-rays reaches the patient several things happen-Most of the useful x-ray beam is absorbed in the tissues of the area under investigation-Some of the x-rays are scattered by this tissue.

-The transmitted beam then reaches the dental x-ray film placed in the mouth and produces a latent image of the teeth being x-rayed. The control panel may be integrated with the x-ray machine tube head support or it may be remote from the unit mounted on a shelf or wall. There are 3 major controls that may be operated or will be pre-set on most dental x-ray machines TF.

False - There are 5. The lead radiation shield protects and supports the anode. It absorbs isotropic direction-independent x-ray photons hence reducing the leakage of radiation.

It is also acts to concentrate the electrons so they escape through the little hole that has been created in. Start studying DA 230 X-Ray Tube Tubehead Parts and their Functions. Learn vocabulary terms and more with flashcards games and other study tools.

Chapter 1 provided a general discussion of the x-ray tube head assembly and the function of the major parts of the design. Chapter 4 discussed the components of the x-ray circuit and the events that lead to the production of x-rays in the x-ray tube. This chapter examines the x-ray tube itself its general construction and how it works.

The sole purpose for manipulating electricity in an x-ray circuit. The tube head fig. 1-3 contains the X-ray tube and other components necessary for generating X-rays.

When an exposure is made X-rays pass through an aluminum filter that screens out unnecessary radiation. Angulation scales are on both sides of the tube head for precise positioning technique. The cylinder or cone is affixed to the tube head and is used to align the tube head with.

Cathode is the negative side of the X-ray tube and consists of the following two parts. The filament is embedded in a metal cup called the focusing cup. The purpose of the focusing cup is to.

The next component of the x-ray tube is the glass envelope. The type of glass that is used in the construction of x-ray tubes is pyrex. This is the same type of glass that is used in cookware which can tolerate tremendous heat levels.

It is important to understand that when x-rays are generated tungsten is vaporized from the target. We have new used and refurbished dental x-ray parts for sale. Parts for manufacturers like Belmont Dent-X Gendex Philips Planmeca Siemens and more.

If you dont see the manufacturer of the part you need please let us know by completing this request. Please check back often as we are continually updating our parts department. An X-ray tube is basically a vacuum tube that produces X-rays which are used in X-ray machines.

X-rays are part of the electromagnetic spectrum an ionizing radiation with wavelengths shorter than ultraviolet light. X-ray tubes evolved from experimental Crookes tubes with which X-rays were first discovered in the late 19th century. The discovery of this controllable source of X-rays.

Guilbaud Education Director School of Radiologic Technology 2. X-Ray Tube Electrical device used for the generation of x-rays. The X-ray tube Figure 2 is the source of high-energy X-ray photons used to excite characteristic fluorescence radiation in the sample.

The X-ray flux is generated when a beam of electrons emitted from an incandescent filament is accelerated through a large potential difference normally in the range 20100 kV and directed at a metallic anode. The major x-ray tube components are the cathode and anode assemblies the tube envelope the rotor and stator for rotating anode systems and the tube housing. The design of the x-ray tube determines the basic characteristics of the x-ray beam such as focal spot size x-ray field uniformity and the x-ray energy spectrum.

These x-ray beam characteristics are important because. X-rays are generated in an x-ray tube. The purpose of the x-ray tube is to produce a controlled x-ray beam.

The tube must be responsive to manual control so that both the amount and the penetrating power of the radiation produced are accurately controlled. To better understand the x-ray tube we need to consider the necessary elements for the production of x-rays. - Tube head and cylinder short cone.

The X-ray beam passes from the aluminum filter through an opening in a lead diaphragm which restricts the beam to 26 inches at the cylinder tip. There are two commonly used cylinder lengths. The Dental X-ray Tubehead By Joan Rohrer.

Learners examine the components of the x-ray tubehead a sealed heavy metal housing that contains the x-ray tube that produces dental x-rays. This object is designed to help students understand the functions and safety features of the tubehead. The positive terminal of an x-ray tube is called the anode it serves three important functions 1 it provides a complete circuit for purposes of accelerating the electrons 2 it houses the target material and 3 it helps to cool the tube.

We already mentioned before that the generation of X-rays generates a tremendous amount of heat. Label the Dental X-ray Tubehead Screencast By Joan Rohrer. The tubehead is a sealed heavy metal housing that contains the x-ray tube that produces dental x-rays.

This learning object will provide students with practice identifying and labeling the dental x-ray tubehead.
