RADIOFREQUENCY (RF) - ELECTROMAGNETIC RADIATION LOWER IN ENERGY THAN INFRARED. THE RF USED IN MRI IS IN THE FORM OF A BURST OF RF ENERGY (PULSE) I THE 10 MHZ TO 100MHZ RANGE RF PULS, DELIVERED TO THE PATIENT BY RF TRANSMITTER. THE RF FREQUENCY, AT THE LARMOR FREQUENCY, RESULTS IN ROTATION OF THE NET MAGNETIZATION VECTRO AND PHASE COHERENCE OF THE NUCLEAR SPINS. AN RF COIL IS USED FOR TRANSMITTING AND RECEIVING MRI SIGNALS (RF). FRINGE FIELDS - WEAKER MAGNETIC FIELDS THAT ARE AWAY FROM THE I...
