Temperature rise modelling framework for multiple electrode configurations on parallel transmit systems.

Implanted electrodes can induce unsafe heating during MRI. Developing safe MRI protocols can be a burdensome process, involving intensive simulations that are hard to tailor to individual patients. To increase the feasibility of safe imaging of patients with implanted electrodes, we extend previous work, that nulled induced currents when the number of transmitters exceeded the number of electrodes, to account for the case when these are equal or the number of electrodes exceeds the number of transmitters. In such cases, complete nulling (no measured temperature rise) is impossible in all electrodes unless an acceptable induced temperature rise is allowed.
