Radio frequency coil device and magnetic resonance imaging system

摘要

An RF coil device and an MRI system are provided. The RF coil device includes m coil elements, where m is an integer greater than 1. The RF coil device also includes an RF switch control unit including n output terminals and m input terminals connected to the m coil elements, respectively, where n is an integer greater than or equal to 1 and less than m. The RF coil device includes a decoder for outputting a control signal to the RF switch control unit according to a received control command. The RF switch control unit connects each of not more than n input terminals to a different output terminal according to the control signal.
