DOI: 10.1002/jmri.27044
Abstract: MRI exams for patients with MR‐conditional active implantable medical devices (AIMDs) are contraindicated unless specific conditions are met. This limits the maximum specific absorption rate (SAR, W/kg). Currently, there is no general framework to guide… read more here.

DOI: 10.1109/temc.2019.2938908
Abstract: Impedances of different portions of active implantable medical devices (AIMDs) can influence its magnetic resonance imaging (MRI) radio-frequency (RF) safety dramatically. To better understand this behavior, in this article, we analytically derive relationships between the… read more here.

DOI: 10.3390/bioengineering10050625
Abstract: Delamination at heterogeneous material interfaces is one of the most prominent failure modes in active implantable medical devices (AIMDs). A well-known example of an AIMD is the cochlear implant (CI). In mechanical engineering, a multitude… read more here.
