A radio frequency (RF) detector array and a MRI system are provided. The
detector array comprises a plurality of conductive array elements being
substantially parallel to a conductive ground plane, a plurality of
capacitors, wherein at least one capacitor is shunted from each array
element to the ground plane to adjust a corresponding electrical length of
each conductive array element, and, wherein a combination of each
respective array element, at least one corresponding capacitor and the
ground plane forms a resonator that resonates at a selected frequency. The
detector array further a decoupling interface, and a plurality of matching
boxes for matching each decoupled conductive strip to a selected
impedance. A MRI system is provided including a detector array as
described herein to produce MR images of the object to be imaged.
