Join the Department of Electrical and Computer Engineering in this ECE Colloquia seminar featuring University of Houston's Ji Chen. 

Patients with implantable devices are often prohibited or restricted for MRI procedure. The concerns come from the potential hazards due to the interaction between electromagnetic fields and implantable devices. In this talk, a general overview of implantable device safety under MRI environment will be presented. One of the major concerns, the RF induced heating for implantable devices will be discussed in detail. In particular, we will present techniques to evaluate the RF induced heating for pacemaker/neurostimulator leads inside human body and the impact of multi-channel RF transmitting system on device heating. Based on rigorous electromagnetic modeling and experimental investigations, the RF induced heating for implantable devices can be captured accurately.
