Abstract
A radio frequency (RF) coil comprises a lay-out of electrical conductors including several axial rung 11s and several circumferential rings (12), in which at least one of the rung 11s is coupled with at least one of the rings by a T-shaped connector. The T-shaped connector includes a distributed capacitive coupling between the ring (12) and the rung (11).
Claims13
A radio frequency (RF) shield comprising:
- two concentric cylindrical tubes each of a conductive layers interspaced with a dielectric;
- a first conductive layer segmented into a set of two or more longitudinal strips;
- a second conductive layer segmented into a set of two or more circumferential hoops, wherein:
- a large mesh of smaller coupled capacitors exists in the segmented first and second conductive layers;
- and sets of longitudinal strips and circumferential hoops cross to form overlapping areas of a network of smaller capacitances to cause sufficient uninhibited flow of RF currents for the shield to function as an RF shield.
