RF-induced currents in stents may cause substantial heating in the surrounding tissue. A precise theoretical calculation of the scattered E-fields is desirable, as heating hot spots occur near the stent surface, which often cannot be measured directly. In this study we present a theoretical model of the scattered E-field of stents and compare it to both electro-optic E-field measurements and MR thermometry. The results demonstrate that the scattered E-field patterns of stents can be precisely calculated from the theoretical model.
