Head RF Coil Design with Surface Current Density Optimization for SENSE Imaging

We have designed and implemented an MRI RF coil that is optimized for SENSE imaging. Our approach solves the inverse problem where the B1 field is calculated to maximize SNR (hence minimize g-factor) within a target volume. We have implemented this with two different approaches. The first one models the coil with positions of vertices of coil conductor segments. In the second approach, which is described here, a finite element mesh is defined on a coil frame and the surface current density is calculated to generate the desired B1 field within the VOI.
