Magnetic resonance imaging system using coils having paraxially distributed transmission line elements with outer and inner conductors

A magnetic resonance imaging system comprising:

• (a) a housing providing a medical diagnostic chamber with a static homogenous magnetic field for a subject therewithin lying along an axis;
• (b) a plurality of transmit/receive inductor systems about said axis in proximity with said housing;
• (c) a gradient inductor system operatively associated with said transmit/receive inductor systems;
• (d) a static magnetic field inductor system operatively associated with said transmit/receive inductor systems;
• (e) at least one of said transmit/receive inductor systems constituting a coil having an outer surface about said axis and including a series of electrical transmission line elements paraxially distributed with respect to said axis about said subject, each of said transmission line elements including an outer conductor and an inner conductor, said inner conductor being spaced from said outer conductor in a direction perpendicular to said outer surface;
• (f) each said coil selectively transmitting to said subject fields of radio frequency energy, and selectively receiving from said subject fields of magnetic resonance energy;
• (g) said gradient inductor system initiating perturbations in said fields and producing signals derived responsively from said perturbations;
• (h) said signals corresponding to spatial indicia derived from said subject.
