Radio-frequency coil for magnetic resonance device

A radio-frequency coil for a magnetic resonance device, comprising:

• i. 2n of curved antenna units, wherein n is an integer of 1 or more;
• ii. conductor end ring segments connected to two ends of the antenna units;
• and
• iii. capacitors connecting adjacent end ring segments,
• wherein each antenna unit of the 2n of antenna units is curved the same as or similar to each other in a plane parallel to a direction of a static magnetic field B0, and all the 2n of antenna units are not intersected with each other;
• when viewed in the direction of the static magnetic field B0, the 2n of antenna units are radially distributed, adjacent antenna units are spaced apart from each other at an angle, and all the antenna units as a whole form a symmetrical array;
• an overall profile of the radio-frequency coil, defined by the curved antenna units, is a dome shape curved surface, and is open on its bottom side, wherein the open side is formed by connecting the end ring segments at two ends of the antenna units and the capacitors in series alternately.
