| Abstract | The phenomenon in which the nuclear spins generate or emit elec tric signals of a specific frequency (Larmor frequency) in a static magnetic field is called nuclear magnetic resonance (NMR). The electric signal (NMR signal) itself carries no spatial infor mation. The spatial information necessary to generate an image is given by magnetic field gradients that are generated by gradient coils. Because they are driven by pulsed electric currents in a strong magnetic field, the coils receive a repetitive strong force, and a loud sound is produced during the MRI scan.
