Abstract
The present disclosure relates to a radio-frequency coil for a magnetic resonance device, comprising: antenna units, conductor end ring segments connecting the antenna units, and capacitors. Here, a single antenna unit is curved in a plane parallel to a direction of a static magnetic field B0 (the positive direction of the z axis); the cross sections of all the antenna units in a x-y plane are spaced apart from each other at an angle and distributed symmetrically in a radial array; adjacent antenna units are connected with the end ring segments and the capacitors at two ends; the coil as a whole is an open dome shape surface structure and is sufficiently conformal to the surface of an object to be scanned.
