radiofrequency

 [ra″de-o-fre´kwen-se]
radio frequency.

ra·di·o·fre·quen·cy

(rā'dē-o-frē'kwen-sē),
1. Radiant energy of a certain frequency range; for example, radio and television employ radiant energy having a frequency between 105 and 1011 Hz, whereas diagnostic x-rays have a frequency in the range of 3 × 1018 Hz.
2. In magnetic resonance imaging, the energy applied to switch or create a gradient in the magnetic field.
