<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional radio frequency coil is unsuitable for exciting and detecting a signal using magnetic resonance. <P>SOLUTION: A current unit having two or more current paths allows control of magnitude, phase, timing, frequency and position of each of element in a radio frequency coil. For each current element, the current can be adjusted as to a phase angle, frequency and magnitude. Multiple current paths of a current unit can be used for targeting multiple spatial domains or strategic combinations of the fields generated/detected by combination of elements for targeting a single domain in magnitude, phase, timing, space and frequency. <P>COPYRIGHT: (C)2013,JPO&INPIT |
