At 64 and 127 MHz for insulated stainless steel wires with an insulation diameter of 1.46 mm, we evaluated the dependence of RF-induced power deposited at a hotspot (p) on wire and tip electrode diameters. The lead electrical length, the transfer functions obtained with 3-D electromagnetic simulations and the power deposition p significantly depended on wire diameter and substantially on tip electrode...
We investigated RF-induced power deposition (p) generated by insulated leads with different lengths located in proximity to two tissues. The first tissue surrounding the leads was shaped as a cylinder with a diameter of 11 mm and located in a very large box filled with the second tissue. Lead electromagnetic models and p substantially depended on electrical properties of both tissues. If the cylinder...
Radio frequency (RF) induced power deposition near straight insulated leads excited by different incident electrical field profiles was investigated. 3-D electromagnetic (EM) simulations were used to obtain implant models as well as RF-induced power depositions calculated as the integral of power loss density. For the investigated setups up to 400% discrepancy between the implant model predictions...
We investigated RF-induced power deposition (p) generated by insulated leads with different lengths surrounded by lower permittivity medium (LPM). 3-D electromagnetic simulations were used to obtain p and leads electromagnetic models. Lead electromagnetic models and p substantially depend on electrical conductivity of LPM. It is impossible to define one test set-up surrounded by LPM that results in...

Radio frequency (RF) induced power deposition of insulated leads was investigated. 3-D electromagnetic simulations were used to obtain leads electromagnetic models as well as RF-induced power depositions at lead tip. The lead electromagnetic models and power depositions substantially depended on lead wire diameter and length of lead tip bare segment. It is impossible to define the worst-case lead...
