End ring port structure of an atypical radio-frequency coil of a magnetic resonance imaging system

摘要

An end ring port structure of an atypical coil for a magnetic resonance imaging system, has an end ring, provided with multiple end ring capacitance positions for disposing equivalent capacitances, with a portion of the equivalent capacitances being formed by two or more split capacitors. A first port has a first leg and a second leg, which are each connected to the end ring. A second port has a third leg and a fourth leg, which are each connected to the end ring. A first capacitor bank is arranged on the end ring between an end ring connection point of the first leg and an end ring connection point of the second leg. The first capacitor bank has at least two capacitors not all belonging to the same end ring capacitance position. A second capacitor bank is arranged on the end ring between an end ring connection point of the third leg and an end ring connection point of the fourth leg. The second capacitor bank has at least two capacitors not all belonging to the same end ring capacitance position.
