Power of RF emissions in a MRI system - jmgarin - 12-15-2016 12:54 PM
What importance has the power of RF emissions in a MRI system?
I would like to ask about the importance that has the power emission of RF amplifier in MRI. Between a 10kW amplifier and another 15kW, what impact it has on the images of MRI, price, speed, etc.?

Radio frequency coils (RF coils) are the receivers, and sometimes also the transmitters, of radio frequency (RF) signals in equipment used in magnetic resonance imaging (MRI). The MR signal in MRI is produced by the process of resonance, which is the radio, there is very little RF interference produced by the MRI machine.Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology My website to form .Certain atomic nuclei can absorb and emit radio frequency energy when placed in an external magnetic field.As a result of dB/dt limitation, commercial MRI systems cannot use the full rated power of their gradient amplifiers.
