Design of a four-channel array coil for dual high-resolution rat knee MR Imaging

In Magnetic Resonance Imaging (MRI), multi-channel coils are extensively used to improve Signal-to-Noise Ratio (SNR) in order to increase spatial and/or temporal image resolution. Recent decoupling techniques based on common conductor that do not require additional preamplifier for the decoupling between elements was achieved for the conception of two-channel surface transceiver coils (1-2). In this paper, based on this common conductor decoupling technique (3), a topology of a four-channel coil was described. Based on this concept, a four-channel surface receiver coil was designed to achieve simultaneous acquisition of both rat knee joints at 7T
