Magnetic field gradient applied during the period when the receiver components are on. The application of this gradient, which is active during the period when the echo is being formed, results in the frequency encoding of the object being imaged.
Also called frequency encoding gradient.

A gradient pulse designed to dephase low spatial frequency components in an image. The simplest such design is to choose the gradient strength so that a linear phase change of -p to p is generated across the image.

A gradient waveform, which will act on any stationary spin on resonance between two consecutive RF pulses and return it to the same phase it had before the gradients were applied.
