What is the main purpose of helium?
helium is used to cool superconducting magnets in mri scanners as helium is lighter then air airships use them as gasses
How is helium use by hospitals?
for MRI machine
In which jobs do you need a knowledge of magnetism?
Health care professionals who operate MRI scanners. Also some paedophiles.
Can you put helium in latex balloons?
Ultimately, you shouldn't try it unless you have a very reliable regulator, are aware that helium has a different displacement than that of air, and have a sense of self-control. Embolisms are not something to be taken lightly whatsoever.
What is one important use for helium?
Helium is an important natural resource, and is used in a variety of settings. One of these is its use in cooling the powerful magnets used for NMR and MRI, where liquid helium is required in order to achieve their operating temperatures. Another key use is as a carrier gas for Gas Chromatography and GC/MS in analytical and similar laboratories.

Why liquid helium is used in body scanners?
The "body scanners" that use it are Magnetic Resonance Imaging, or MRI, machines. (The scanners at airports are akin to radar sets, and don't use liquid helium.) MRI machines contain a very large electromagnet. To keep the thing from requiring its own power plant, an MRI magnet is wound with superconducting wire - wire with, effectively, no resistance. Superconducting wire must be kept at the temperature of liquid helium if you want it to superconduct.
What equipment do forensic laboratories use?
mri scanners, x-rays, finger-print scanners, ect.
How is helium use by hospitals?
for MRI machine
What do you mean by quench in relation to MRI scanners?
Most of the MRI scanners today use superconducting magnets that need liquid helium to keep them cold enough for proper function. A malfunction may, however, cause the helium to convert to gas and rapidly escape the cryogenic chamber that effectively demagnetizes the main MRI magnet. When this happens, a MRI magnet is said to have "quenched". This not only incurs expensive repairs to the equipment but the rapidly escaping helium in the close confines of a MRI suite may also cause asphyxiation injury to any person present there. Fortunately this catastrophe is extremely rare and has been virtually eliminated in the newer equipment through improved design.

Does a dog have to be shaved for an MRI?
No, MRI scanners can 'see through' hair
What are 2 jobs that use magnets?
MRI Scanners that are used in the hospital i guess a medical technician
What does MRI stand for MRI scanners?
Magnetic Resonance Imaging
Do MRI scanners have any adverse effects?
MRI scanners have practically no adverse effects. MRI or magnetic resonance imaging works by noting difference of various images created by varying response of different body tissues.
What kind of tools does radiologist use?
radiologists use x-ray equipment radiologists use x-ray equipment They use MRI scanners, CAT scanners, they do ultrasounds(I don't know name of machine), and they take x-rays!
Where can you go to school to learn to operate an MRI scanner?
MRI scanners are easy to operate. However if you want to go to school to learn more details about scanners you can join a vocational school that lets you know information like that.
