An investigation of alternating impedance microstrip transceiver coil arrays for MRI at 7T

Summary form only given, as follows. The magnetic field generated by a conventional MSR is inhomogeneous along the resonator axis. It is strong at the center and weak at the terminating ends. To homogenize the B1+ field, it is required to modify the traditional MSR. Recently, an approach based on alternating impedance MSR has been presented. Another configuration of alternating impedance MSR is proposed. Results indicate that, the alternating impedance MSR with circular elements is the best coil in terms of B1+ field homogeneity.
