具有优化的RF发射和接收能力的MRI系统
摘要：
本公开内容涉及一种磁共振成像系统(100)，所述磁共振成像系统包括：主磁体(104)，其用于在成像区(108)内生成主磁场；射频RF天线(114)，其包括RF输入端子(300)和RF输出端子(302)；RF系统，其用于向所述RF输入端子(300)供应射频功率以激励所述天线(114)，所述天线(114)还适于拾取来自所述成像区(108)的磁共振信号(144)；数据采集系统(126)，其用于接收来自所述RF输出端子(302)的所述磁共振信号(144)；其中，所述RF输入端子(300)被电流连接到所述天线(114)，并且所述RF输出端子(302)被感应耦合到所述天线(114)。
摘要（英）：

The present disclosure relates to a magnetic resonance imaging system (100) comprising a main magnet (104) for generating a main magnetic field within an imaging zone (108); a radio frequency, RF, antenna (114), comprising an RF input terminal (300) and an RF output terminal (302); an RF system for supplying radio-frequency power to the RF input terminal (300) to energize the antenna (114), the antenna (114) being further adapted for 5 picking up magnetic resonance signals (144) from the imaging zone (108); a data acquisition system (126) for receiving the magnetic resonance signals (144) fromthe RF output terminal (302); wherein the RF input terminal (300) is in galvanic connection to the antenna (114) and the RF output terminal (302) is inductively coupled to the antenna (114)
