What else can I help you with?
Does a dog have to be shaved for an MRI?
No, MRI scanners can 'see through' hair
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 equipment do forensic laboratories use?
mri scanners, x-rays, finger-print scanners, ect.
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.
Why do MRI scanners use helium?
Liquid helium is used to cool the superconducting electromagnets.
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.
Do you stand for the MRI scan?
Magnetic resonance imaging.
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
Nuclei excited by an rf pulse?
Yes, a magnetic resonance imaging scanner uses an RF pulse to excite nuclei in the body. Practically all medical MRI scanners are tuned to excite hydrogen nuclei. Other MRI scanners used in physics and chemistry labs are tuned to excite other nuclei -- see the links for a detailed list.
What new technology may replace CAT scanners?
One potential technology that may replace CAT scanners is magnetic resonance imaging (MRI) machines. MRI machines provide detailed images of the body's internal structures without using ionizing radiation, making them safer for patients. Additionally, advancements in machine learning and artificial intelligence may enhance the capabilities of MRI technology in the future.
How has the development of mri scanners advanced medical diagnosis and treatment?
Its made it easier to see sction of the body which we couldnt see with regular x ray.
The super-cold liquefied gases used in MRI scanners?
The super-cold liquefied gases used in MRI scanners, primarily liquid helium, are crucial for cooling the superconducting magnets that generate powerful magnetic fields. These magnets must be maintained at extremely low temperatures to achieve superconductivity, which is essential for the MRI's high-resolution imaging capabilities. Liquid helium is particularly favored due to its low boiling point and ability to maintain the necessary cryogenic environment. Efficient use and management of these gases are vital for the optimal performance and cost-effectiveness of MRI systems.
