Transfer function method was utilized to evaluate the RF-induced heating of implantable lead with 137 implanted lead trajectories under different shimming conditions. A coated wire is used to emulate medical leads. Two different shimming conditions were studied. One is to optimize the homogeneity of the B_(1+) field magnitude in human heart region, and second one is to estimate the possible worst-case...
One of the critical MRI safety concerns for patients with medical implants is the RF coil induced heating in the vicinity of electrode lead tip. Many works have been carried out to assess such risk for fully implanted leads. However studies on partially implanted, as well as minimally implanted electrodes have not been explored. In addition, effects of statures, weight, ages and many other factors...
