Abstract

NMR coils are formed from transmission line comprising a tuned LC circuit determined substantially from the distributed capacitance and inductance of the transmission line operated in common mode. Introduction of gaps staggered between opposite conductors of 2-conductor transmission line contribute a desired distributed capacitance with reduced effective inductance to sustain resonant behavior at higher frequency than achievable with conventionally tuned coils and with relaxation of dimensional constraints as the resonant half wavelength approaches coil dimensions.

Claims

comprising said second electrical conductor whereby four resonant circuits are supported by said 4 terminal transmission line.
6. The multiply tuned coil of claim 5, wherein said coil is a surface coil.
7. An NMR apparatus for study of the nuclear spins of an object, said apparatus comprising: a magnet for producing a polarizing magnetic field Bo, at least one RF transmitter to provide RF energy for excitation of magnetic resonance, an RF receiver for detection of a magnetic resonance signal; and a controller for coordinating excitation and acquisition of said RF signal; and a surface coil for coupling one of said RF transmitter or receiver to a localized aggregate of said nuclear spins, said surface coil comprising a 4 terminal transmission line disposed to support a common mode RF current through a pair of active common mode terminals, said transmission line comprising first and third terminals comprising one inductor of said transmission line, second and fourth terminals comprising another inductor of said transmission line, said one and another inductors capacitively coupled through distributed capacitance therebetween, at least one pair of said capacitively coupled terminals comprising a first resonant circuit therebetween and at least one other pair of said four terminals comprising a second resonant circuit therebetween.
8. The NMR apparatus of claim 7, wherein said other pair of terminal comprises an inductively coupled pair of said 4 terminals.
9. The NMR apparatus of claim 7, wherein said other pair of terminals comprises another pair of capacitively coupled terminals.
