摘要： In one embodiment, an RF coil device includes a base board, a belt member, a first coil element, a second coil element inside the base board, and a connecting unit. Both ends of the belt member are respectively connected to mutually separated places on the base board, so that the center part of the belt member is located on the anterior surface of the base board. The belt member is curved to form airspace between the center part thereof and the anterior surface for letting an arm pass through in interdigitation state. The first coil element includes first and second partial coils inside the belt member, and becomes a loop coil element by their connection. The connecting unit detachably connects the base board to the belt member, and mutually connects the first and second partial coils in the interdigitation state.

摘要： A radio-frequency coil has a first element and a second element both being adjacently arranged so as to nip a division/join portion. The first element has a first main loop portion provided along an arrangement plain surface and a first sub-loop portion provided along a surface substantially perpendicular to the arrangement plain surface. The second element has a second main loop portion provided along the arrangement plain surface and a second sub-loop portion provided facing the first sub-loop. The first sub-loop portion and the second sub-loop portion generate an induced electromotive force such that, among magnetic fields generated when a current flows in one coil, a summation of the magnetic fields, which interlink with the other coil, becomes zero.
摘要翻译：射频线圈具有相邻设置的第一元件和第二元件，以便夹持分割/连接部分。第一元件具有沿着布置平坦表面设置的第一主环部分和沿着大致垂直于布置平面的表面设置的第一子回路部分。第二元件具有沿着布置平坦表面设置的第二主环部分和面向第一子回路设置的第二子回路部分。第一子回路部分和第二子回路部分产生感应电动势，使得当电流在一个线圈中流动时产生的磁场中，与另一个线圈相互连接的磁场的总和变为零。
