Claim:
1. A multiple channel nuclear magnetic resonance (NMR) coil, operating at a resonance frequency f 0 , comprising: five or more closed signal channels, each comprising a unit loop, the unit loops being arranged on and surrounding a cylindrical surface of a periphery of an imaged region, and each unit loop comprises: two vertical conducting parts parallel to a cylinder axis; and two arc-shaped conducting parts perpendicular to the cylinder axis; wherein the vertical conducting part of the unit loop comprise an inductor and a capacitor connected in serial, forming a resonant circuit with another inductor and capacitor in an adjacent unit loop or a nonadjacent unit loop separated by one unit loop to decrease coupling between signal channels of adjacent unit loops or nonadjacent unit loops separated by one unit loop; and a plurality of inter-loop capacitors configured to respectively connect the two arc-shaped conducting parts disposed on one same side of adjacent unit loops to decrease coupling between multiple signal channels.
