The safety assessment of RF exposure in MRI heavily relies on electromagnetic simulations. As there are numerous different coil designs on the market, this assessment is typically performed with sets of generic coil geometries to cover the commercially available bore diameter and coil lengths. This abstract investigated the effect of other design parameters, which are currently less considered. Our results show that feed-port positioning and non-ideal tuning of the coil may considerably alter the RF absorption pattern in an oval phantom, and even more so the E-field distribution outside the phantom.
