There are at least two types of NMR equipment. One uses a very strong constant magnetic field that is perterbed by RF electric field pulses, and the other uses Earth's magnetic field that is perterbed by RF electromagnetic pulses.
The received echos of the pulses are analyzed and computer aided tomography techniques are used to compose the images.
Several new brain-oriented helmets have been developed recently where the coils are built right into the shell of the helmet. Again, the echos of the electromagnetic pulses are analyzed and imaged. The number of coils on the helmet that I saw in pictures seemed to have fewer than 90 fairly large guage conductors located all over the shell of the helmet. The images taken with the helmet were comparatively better than those of a competing NMRI medical imager, revealing much higher levels of both resolution and quantization (of color graduation) detail that would permit seeing much smaller abnormalities and structures.

What is resonance relating to nmri?
In the context of nuclear magnetic resonance imaging (NMRI), resonance refers to the absorption of radiofrequency energy by atomic nuclei in a magnetic field. When the applied radiofrequency matches the resonant frequency of the atomic nuclei, it causes them to resonate and emit signals that can be detected and used to create images of the internal structures of the body.

Is magnetic resonance resulting from nuclear reactor?
No, a nuclear reactor produces thermal energy and ionising radiation, no magnetic effects.
How is Nuclear Magnetic Resonance used in the medical field?
Nuclear Magnetic Resonance is often used in the Radiology modality of MRI, which stands for Magnetic Resonance Imaging. Nuclear Magnetic Resonance is an alternative to radiation producing techniques such as the traditional Anode/Cathode X-ray tube. NMR is used to help to visualize patient anatomy and pathology without delivering the harmful effects of ionizing radiation used in other modalities.
