Combination of travelling wave approach and microstrip transceiver coil arrays for MRI at 7T

Summary form only given, as follows. To homogenize the B1+ field and decrease SAR for MRI at 7T, more degrees of freedom are needed and different excitation approaches are required. Microstrip array is a promising approach for excitation and reception at 7T. Travelling wave is another approach for excitation based on propagating modes excited from an antenna. A combination of the two excitation approaches is presented. Results indicate that such a combination can increase the B1+ field homogeneity and decrease SAR at 7T.
