Excerpt

Despite its importance as a diagnostic tool, patients with active implantable medical devices (AIMDs) are generally denied access to magnetic resonance imaging (MRI). Numerous scan parameters and a multiplicity of fields yield a complex MR environment for device safety assessment. Computational human models are used to quantify the RF-induced energy at the AIMD ports during the evaluation of RF-induced malfunction and unintended stimulation hazards. This work discusses this process, with an in-depth investigation of the RF-induced voltage at the AIMD antenna.
