RF RF Decoupling method for radio frequency coil array for magnetic resonance imaging and radio frequency coil assembly for magnetic resonance imaging and magnetic resonance imaging system

摘要

The present invention relates to a radio frequency (RF) coil decoupling method for magnetic resonance imaging (MRI), an RF coil assembly, and an MRI system thereof. The RF coil decoupling method comprises the steps of: arranging multiple closed circuit surface coils in two layers; arranging the individual closed circuit surface coils to overlap one or more other closed circuit surface coils arranged on the upper or lower layer thereof; arranging the individual closed circuit surface coils to have an overlapping area with the other individual closed circuit surface coils while arranging the overlapping area to occupy 25-49% of the entire inner area thereof; connecting the individual closed circuit surface coils with other adjacent closed circuit surface coils through one or more selected from a group including two to ten capacitors, inductors, and transformers as a medium when there are closed circuit surface coils arranged in parallel in the same layer; and making the individual closed circuit surface coils include two to twenty capacitors in the closed circuits.
