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.


(1) (Phase Encoding) An early magnetic encoding method used on 1600 bpi tapes in which a 1 is an up transition and a 0 is a down transition in the center of the bit cell.

(2) (Processing Element) One of multiple CPUs in a parallel processing system.

(3) (Professional Engineer) An engineering licensure based on a combination of education and experience. Although each state varies its regulations, the minimum requirements are a four year engineering degree from an accredited school, four years of professional engineering experience and successful completion of two stringent exams along the way. It is estimated that only about 20% of practicing engineers in the United States are licensed.

For instance, one such PPI technique known as sensitivity encoding (SENSE) utilizes complex RF coil sensitivity profiles to improve the image quality or accelerate the image acquisition time by substituting gradient encoding [12, 13].
In this novel research study, we demonstrate that the RRFC transmit concept can be successfully applied to [B.sup.+.sub.1] gradient encoding using either linear or nonlinear RF gradients.
Experimentally demonstrated spatial resolution of [B.sup.+.sub.1] gradient encoding has shown to be much higher than that provided by RF receive coil array sensitivity encoding (SENSE) alone but lower than generally achievable with [B.sub.0] gradients [18].
