Abstract
A coil system for a magnetic resonance imaging (MRI) system includes a plurality of adjacent surface coils for sensing magnetization in a patient. Switches are provided for enabling selected ones of the plurality of coils to output electrical signals. A signal combiner combines the electrical signals from the selected coils into an output signal for further processing. Coupling cancellation networks are provided between adjacent ones of the plurality of coils for cancelling electrical coupling existing therebetween.
