Hi,

Which frequencies does an MRI machine use? Is it microwaves?
Would prolonged exposure to it be damaging to the body?

The actual signal information that is used for reconstructing the MRI images comes from radio-frequency (RF) magnetic fields, oscillating millions of times per second (MHz range).

The FDA and other advisory bodies have recommendations for limiting things such as the rate of switching of the RF gradient fields and the RF power levels, but I think the current consensus is that these things do not pose serious risks to the patient as used in MRI.

That was wonderful.

Nuclear Magnetic Resonance imaging is actually a very advanced concept...it involves quantum mechanics and was worthy of a nobel prize.

Enjoy the reading

An MRI machine uses radio waves to produce detailed images of the body's internal structures. These radio waves have frequencies in the range of 1 MHz to 1 GHz, which is much lower than the frequency of microwaves. Therefore, an MRI machine does not use microwaves.

As for the safety of prolonged exposure to an MRI machine, there is no evidence to suggest that it is harmful to the body. MRI machines use non-ionizing radiation, which does not have enough energy to cause damage to cells or DNA. However, it is important to follow safety protocols and guidelines to minimize any potential risks, such as removing metal objects from the body and limiting the number of scans a person receives. Overall, the benefits of MRI imaging far outweigh any potential risks.
