Microstrip receivers are designed as half-wave or quarter-wave resonators, aligned along the axis of the static magnetic field. The long wavelengths at imaging frequencies result in coils that are too long to be arrayed in the superior/inferior direction, and these receivers are typically arrayed only in the left-right and/or anterior/posterior directions. Using short microstrip receivers, we demonstrate parallel imaging with accelerations in the S/I direction. The length of microstrip resonators is reduced using two different methods at 3.0T: 1) a hybrid design incorporating lumped elements 2) a design that alternates between microstrips and coax lines of the same characteristic impedance.
