During an MRI scan, the radiofrequency field from the scanner's transmit coil, but also the
switched gradient fields, induce currents in any conductive object in the bore. This makes …

The main risks associated with magnetic resonance imaging (MRI) have been extensively
reported and studied; for example, everyday objects may turn into projectiles, energy …

MRI is a valuable clinical and research tool for patients undergoing deep brain stimulation
(DBS). However, risks associated with imaging DBS devices have led to stringent …

Purpose To assess the mean and variance performance of parallel transmission (pTx) coils
for reduction of the absorbed power around electrodes (APAE) in patients implanted with …

Purpose Elongated conductors, such as pacemaker leads, neurostimulator leads, and
conductive guidewires used for interventional procedures can couple to the MRI …

The purpose of this work is to present a new method that can be used to estimate and
mitigate RF induced currents on Deep Brain Stimulation (DBS) leads. Here, we demonstrate …

Purpose To implement a modular, flexible, open‐source hardware configuration for parallel
transmission (pTx) experiments on medical implant safety and to demonstrate real‐time …

Purpose To introduce a temperature sensor implant (TSI) that mimics an active implantable
medical device (AIMD) for animal testing of MRI heating. Computer simulations and …

Interventional magnetic resonance imaging (MRI) could allow for diagnosis and immediate
treatment of ischemic stroke; however, such endovascular catheter-based procedures under …

Purpose To dynamically minimize radiofrequency (RF)‐induced heating of an active
catheter through an automatic change of the termination impedance. Methods A prototype …
