Keynote Video: Multiphysics Simulation for Patient Safety

Fanny Littmarck | November 30, 2012

The second video in our COMSOL Conference Boston 2012 keynote series features Dr. Alan Leewood’s presentation on the use of multiphysics simulation for medical safety applications. The focus of this presentation is on the safety of passive conductive implants during MRI screenings.

As you will hear in the video, Dr. Leewood works for MED Institute, a medical manufacturing resource serving the COOK Group. COOK is credited with developing and approving the very first coronary stent. Since then, safety of these stents and other long, metallic, conductive devices has been on the forefront of their research. These types of devices are implanted into patients to solve one medical problem, but if heated up beyond 6 degrees Celsius, they can become a problem in themselves.

When a patient is subjected to an MRI scan (which is a super-conducting magnet creating a static magnetic field) implanted stents can heat up. In order to prevent this from happening, MED Institute wanted to predict the device and surrounding cell tissue temperatures to determine safety levels. To meet their goal, they sought out AltaSim Technologies to identify, implement, and validate the appropriate physics in COMSOL. By simulating the RF heating of the implants, they are now able to prevent excess cell death, thus increasing patient safety.

Watch the video above for the full keynote talk. You can also access the slides, without the commentary, for this presentation on the “Use of COMSOL Multiphysics to Simulate RF Heating of Passive Conductive Implants in MRI Scanners”.
