The wave length in tissue at ultrahigh fields allows for practical realization of RF antenna architectures such as dipole elements, high dielectric resonators and slot antennae. This work presents a novel flexible eight channel slot antenna array customized for cardiac MRI at 7.0 T. The proposed array is lightweight, easy to build, and affords a tight fit for a broad range of upper torso geometries while ensuring good matching and tuning. The in vivo study demonstrated the feasibility of the array for high fidelity, whole heart coverage MRI at 7.0 T and showed rather uniform signal intensity across the heart.
