a grid is a device placed in front of the image receptor which only allows xrays to travel directly through from the tube and prevent xrays which have been "scattered" from passing through to the image. This gives a much clearer resulting image. Grids are generally only used on thicker body parts where scattered xrays are more of an issue

What happens when the x-ray tube is to close to the chest for an x-ray?
WHILE TAKING A PA VIEW OF CHEST DISTANCE BETWEEN XRAY TUBE AND FILM IS ABOUT 6 FT SO AS TO DECREASE THE MAGNIFICATION AND INCREASE THE SHARPNESS OF IMAGE WHEREAS AN AP VIEW WHICH IS TAKEN AT LESSER DISTANCE THERE IS INCREASED MAGNIFICATION AND DECREASED SHARPNESS. THEREFORE WHEN the X-ray tube is to close to the chest for an X-ray IT CAUSES 1 INCREASED MAGNIFICATION 2 DECREASED SHARPNESS
What element can be used to produce X - Ray images?
True X rays are not produced by elements- they are produced by an electric current and an X ray tube. However, radioactive elements such as Cobalt and Uranium can be used to produce a radiographic image, and are commonly used to inspect welds in metals, However, they use gamma rays and not X rays.
How do they call the breast X-ray image?
An x-ray of the breast is called a mammogram.
What begins with the letter X in Sweden or has the letter X in it?
x-ray
Sample answers to x-ray tech interview questions?
what kind of relevant experience do you have in the x-ray tech
Grid control X-ray tube versus dual X-ray tube?
A Grid Controlled X-ray Tube is a triode in which a third electrode is introduced between the Anode and Cathode. This electrode is normally neutral so the x-ray production can take place. However, one can decide when to cut the exposure by introducing negative charge on this. This will then stop (repel) the electron from reaching the Anode and x-ray production is stopped. Therefore, the elecrode with a negative charge can as a timer or if chrge is given intermittently, it acts as a device to have flouroscopy in pulses.
How are the X-ray tube and the X-ray machine related?
The X-ray tube is the part of the X-ray machine that emits the X-rays (very high energy photons).
Who invented the x-ray grid?
Dr Gustave Bucky is the original inventor of the x-Ray grid. He made this in 1913. He was born September 3, 1880.
What is the area hit by electrons after they pass across the x-ray tube called?
The area that is hit by electrons after they pass across the x-ray tube is called the target. The x-ray tube contains oil to help dissipate heat.
What is the name of the tube used to produce X-rays?
X ray tube i am not sure but maybe
Why did X Ray refuse to discuss the gold tube with Stanley at breakfast in Holes?
X-ray refused to discuss the gold tube with Stanley because X-ray was afraid the Warden might have been listening.
The purpose of rotating the X-ray tube target is to?
The x-ray tube target is rotated to reduce wear and tear on the anode and to keep the anode from overheating.
What is the filament of an X-ray tube made of?
Rhodium OR Tungsten or Molybdenum ...............................................GHo$t
What is the source of electrons in the x-ray tube?
The cathode of an electron gun.
What are stationary anode x ray tubes?
An x-ray tube where the anode is held still, rather than rotated as would happen in the rotating anode tube.
Does an x-ray tube burn out?
Any 'emitter'--which an x-ray tube is, is subject to burn out, yes. Due to the various types of x-ray tubes, a simple test is beyond the scope of this forum, sorry. See the link for more.
What is the purpose of the beryllium coating on the window of an x ray tube?
The beryllium is not actually a coating on the window of an x-ray tube, it is the window of the x-ray tube. Beryllium is essentially invisible to x-rays, just like glass is essentially invisible to visible light. Just like we use a glass window to let sunlight in and keep the bugs out of our house, x-ray tubes use beryllium windows to let the x-rays get out of the tube and keep the air out of the tube (x-ray tubes have a vacuum on the inside, just like a light bulb does).For more information, take a look at:http://en.wikipedia.org/wiki/Beryllium#Radiation_windows
