Pulsed field gradient - WikipediaA pulsed field gradient is a short, timed pulse with spatial-dependent field intensity. Any gradient is identified by four characteristics: axis, strength, shape and duration. Pulsed field gradient (PFG) techniques are key to magnetic resonance.field gradient magnetic,Magnetic Field Gradients - Q magnetsMagnetic field gradients are the key to the therapeutic effect of static magnets. Here we try to define magnetic field gradients and their effect on nerve tissue.
