Traveling-wave
MRI utilizes the far field of a single piece patch antenna to generate
homogeneous RF field covering large size imaging samples. In this work, we
demonstrate a method to applying the traveling wave technology to parallel
excitation and reception by using a multi-element patch antenna array. Each
array element is a CP patch antenna which generates quadrature RF fields.
FDTD simulation results demonstrate the excellent decoupling among elements,
great g-factors at various reduction factors for 1D SENSE, demonstrating the
feasibility of parallel imaging using traveling-wave.
