phase encoding

[′fāz in′kōd·iŋ] (computer science) A method of recording data on magnetic tape in which a logical 1 is defined as the transition from one magnetic polarity to another positioned at the center of the bit cell, and 0 is defined as the transition in the opposite direction, also at the center of the cell. Also known as Manchester coding.

phase encoding

phase en·cod·ing

in magnetic resonance imaging, the technique of inducing a gradient in the magnetic field in the x or y axis to induce phase differences with location. Synonym(s): gradient encoding

phase encoding

An MRI term for the process of locating an MR signal by altering the phase of spins in one dimension with a pulsed magnetic field gradient along that dimension before acquiring the signal. Because each signal component experiences a different phase-encoding gradient pulse, its exact spatial reconstruction can be specifically and precisely located by the Fourier transformation analysis. Spatial resolution is directly correlated to the number of phase-encoding levels (gradients) used.
