Q.7 MRI machine uses magnetic field to create detailed
images of human soft organs. Can you
elaborate the basic concept of working of MRI scanner? How the
strong magnetic field is
produced in MRI scanner to scan the organs? Discuss the role of
radio waves in MRI machines?
Write down major parts used in MRI machine. What would happen if
the north-pole end of a bar
magnet is held near a positively charged piece of plastic? Justify
your answer. X-ray machine
and MRI machine do the same job of human organ scanning. Analyze
both the machines and
discuss three merits and demerits of it.
