7T Head Coil Testing
In this study, a 7T cylindrical birdcage head coil was investigated to test performance (resonance, B1+ homogeneity, polarisation efficiency, SAR) and interaction with a human head model. Method of Movement (MoM) simulations were initially used to solve energy fields in an empty coil and a coil with a homogeneous head model. A hybrid FEM and MoM approach was also employed for a more detailed simulation of B1+ field distribution. More anatomically accurate head models provided by Simpleware were used to complete these tests, with models featuring an average element edge length of 6.3 mm.
