Abstract:
1. A volume coil assembly for a magnetic resonance imaging system comprising: a plurality of coil units configured to form a volume coil for transmitting or receiving radio-frequency signals in a magnetic resonance imaging system; two adjacent ones of said coil units having respective overlapped portions that eliminate coupling between said two adjacent ones of said coil units; two next-adjacent ones of said coil units, that are separated from each other in said volume coil by one coil unit therebetween, each having an inductor connected therein, and said two inductors being coupled with each other to eliminate coupling between said two next-adjacent coil units; and all of said coil units being collected at one axial end face of said volume coil, and two of said coil units in said plurality of coil units, which are neither said adjacent ones of said coil units nor said next-adjacent ones of said coil units, being connected with each other at said end face, by a connecting circuit selected from the group consisting of capacitance circuits and inductance circuits, that eliminates coupling between said two coil units that are neither said adjacent ones of said coil units nor said next-adjacent ones of said coil units.
