Double-resonance MRI coil

摘要

A double-resonance coil for use in MRI having a coil element, a first input/output terminal coupled to the coil element, and a second input/output terminal coupled to the coil element. A first resonance means is coupled between the coil element and the first input/output terminal to cause the MRI coil to resonate at a first MRI frequency, and a second resonance means is coupled between the coil element and the second input/output terminal to cause the MRI coil to resonate at a second MRI frequency substantially different than the first MRI frequency. The double resonance coil includes a first frequency-blocking means coupled to the coil element for substantially preventing the second MRI frequency from being detected at the first input/output terminal and a second frequency-blocking means coupled to the coil element for substantially preventing the first MRI frequency from being detected at the second input/output terminal.
