It has been demonstrated that integrating ultra-High Dielectric Constant (uHDC) materials with a RF coil can achieve large improvement in RF magnetic field (B1) and imaging sensitivity. A typical configuration inserts the uHDC materials between the imaging object and the RF coil, resulting in a weak B1 from the coil due to the distance from the object. In this study, we explored different configuration options and found that the best arrangement was to place the uHDC materials outside the coil, leaving no gap between the RF coil and the object, for optimal imaging applications.
