,MRI
(magnetic resonance imaging)
How does it work:
• Atoms spin in random directions around individual
magnetic fields
• Atoms line up about halfway and then the atoms go
each way but there are a few unmatched atoms
• When radio frequency pulse is applied unmatched
atoms spin the other way
• The radio frequency is turned off and the extra atoms
return to normal and emit energy
• the energy sends a signal to a computer and using
mathematical formulas then convert the signal to an
image
, FOR DIAGNOSIS

medical field to determine and examine organs, tissues or the
