RF coil

The purpose of the invention is to provide an RF coil with good high-frequency characteristics and flexibility. RF coils in some embodiment comprise three or more electrical conductors that form an RF coil element. The electrical conductors are parallel in the space. Along the length of the radio-frequency coil element, the three or more electrical conductors are separated from each other by respective distances and by one or more dielectric materials. In each of the electrical conductors, the shape of a cross section perpendicular to the length direction is isotropic with respect to the central spindle of each electrical conductor. 目的是提供一种具有良好的高频特性和挠性的RF线圈。有关实施方式的RF线圈具备形成RF线圈元件的3个以上的导电体。上述导电体在空间上相互平行。上述导电体沿着上述RF线圈元件的长度通过独立的多个距离及1个或多个电介质材料相互电气地分离。在上述导电体的每一个中，与上述长度的方向垂直的截面的形状相对于上述导电体各自的轴芯具有各向同性。
