Abstract :
Implantable stents can be used as radiation antennas for wireless communication of cardiovascular health monitoring data. However, such stent can also lead to RF induced heating during MRI procedure. In this paper, we investigate the effect of different stent size on the antenna radiation performance as well as its RF induced heating during MRI procedure. Preliminary investigations show that longer stent typically yields to better radiation efficiency but suffers from higher temperature rises.
