What does radio frequency shielding do for mri's magnetic field?
RF Shielding actually has little to do with the magnetic field generated by an MRI Scanner. The purpose of The RF Shielding installed in an MRI exam room is to prevent radio frequency interference from entering into the MRI Scanner and causing image quality degradation.
What material is used for MRI?
The primary functioning parts of an MRI system include an external magnet, gradient coils, RF equipment, and a computer. Other components include an RF shield, a power supply, NMR probe, display unit, and a refrigeration unit.
What is the risk of rf radiation from an amateur radio transmitter 100 watts or less 1.8 mhz to 420 mhz?
Radio frequency energy causes a heating affect. You can get RF burns if you touch or get really close to a wire carrying RF energy. With powers below 100 watts and normal wire insulation, RF burns are extremely unlikely. Since RF currents flow in the surface of a conductor (your skin), an RF burn is not the same as a burn from a 100 Watt soldering iron (for example). If you position your antenna feeders and antennas out of reach of prying hands, you will be safe.
What wave is used in MRI machine?
i think radio if not x rays but im pretty sure its radio
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.
