Since the introduction of parallel transmission techniques like transmit SENSE or RF shimming, arbitrarily shaped arrays can potentially be used for excitation. Here we present an open U-shaped 8-channel transmit/receive strip line coil for 7 Tesla MRI designed for simultaneous high-resolution and real-time joint imaging of the human ankle. The coil produced high quality, high resolution images of the moving ankle during real-time imaging using an acceleration factor of four in the phase-encoding direction.
