PROBLEM TO BE SOLVED: To provide a shoulder coil for a magnetic resonance system including a receiving part and a transmitting part.SOLUTION: Transmitting parts 1 and 2 are used to be coupled to a radio frequency magnetic field of a total body coil of a magnetic resonance system. A local coil for imaging a shoulder joint in the magnetic resonance system has the transmitting parts 1 and 2 and receiving parts, and since the receiving parts 1 and 2 couple a radio frequency magnetic field from the total body coil, it is not necessary to connect the local coil to the magnetic resonance system through a special transmit cable. Therefore, the local coil has a microstructure, so that the required cost is low. The shoulder coil can form a uniform radio frequency magnetic field region having high intensity, so that the transmit power of the total body coil is lowered to lower the whole specific absorption rate of radio frequency. In a mechanical view-point, the transmitting parts 1 and 2 and the receiving parts of the shoulder coil are freely combined for use, and the receiving parts are used singly or together with the transmitting parts 1 and 2 so as to improve flexibility of application.COPYRIGHT: (C)2014,JPO&INPIT【課題】受信部分と送信部分を備えた、磁気共鳴システムのための肩用コイルを提供する。【解決手段】送信部分1,2は磁気共鳴システムの全身用コイルの無線周波数磁界と結合されるのに用いられる。磁気共鳴システム内の肩関節結像用の局部コイルは送信部分1,2と受信部分を有し、受信部分1,2は全身用コイルからの無線周波数磁界を結合するので、局部コイルは特別な送信ケーブルを介して磁気共鳴システムに接続される必要はない。従って局部コイルは微細な構造を有し、必要なコストは低い。この肩用コイルは、高い強度を有する、均一な無線周波数磁界領域を形成することができ、全身用コイルの送信パワーが低下し、無線周波数の全体的な比吸収率が低くなる。機械的な観点ではこの肩用コイルの送信部分1,2と受信部分は使用のために自由に組み合わされ、受信部分が単独で、または送信部分1,2と一緒に使用され、応用の柔軟性が改善される。【選択図】図1A
