Inside the 'donut' of the MRI machine are a huge number of RF (radio frequency)
sources and RF detectors. After the sources shoot a short, powerful pulse of RF
into you, the sources shut off, and the tissues throughout your body "ring", in
response to the RF they've absorbed, combined with the powerful field of the giant
permanent magnet that's also all around you inside the donut. The detectors
listen to the 'ringing' of your body's tissues from a huge number of different
directions, all around the ring. Each detector hears a ring of a slightly different
level, and hears it fade out after a slightly different time. The signals that are
heard by all of the detectors are compared and combined to give a picture of
what's inside you.
The basic concept of forming the image is the same as in other forms of "tomography" ...
the CT scan, using X-rays instead of RF, and the PET scan, using positron emission
from a radioactive substance.
The math is incredibly complex in each case.
On a completely irrelevant note, but one which I can't bring my self to
conclude without mentioning ... probably my only claim to fame is the fact
that my brother-in-law is one of the names on the original patent granted
to GE for the computed tomography process, and his sister was involved in
some good-science early MRI research when we met in the late 70s. Those
facts and several nickels have bought me many cups of coffee through the
years ever since.
