摘要
Abstract
The paper elaborates the principle and construction of the radiofrequency system of magnetic resonance imager made by Siemens.The system consists of modulator,RF power amplifiers,impedance matching networks,namely,tuning unit,transmitting coils and receiving coils.RF signals are excited and received and processed by the subsystem.The system is one of the best important parts.Meanwhile,the paper exemplifies and analyzes the cause of failures of the system and introduces the ways for its troubleshooting.关键词
