The quantitative analysis of induced E-field due to presence of medical catheter implants during MRI become particularly critical if the implant is only semi immersed into the human body where a part remains outside. As examples, deep brain electrodes are partly immersed into the brain and various EEG and ECG electrodes as zero immersing configurations. As the result of the numerical simulations, SAR distribution in the surroundings of the tip of the generic implants is obtained for 3 configurations under test: partly immersed insulated/uninsulated and fully immersed uninsulated generic implant. Temperature measurements are done for all worst case lengths and two adjacent lengths in an in-house 64 MHz RF laboratory system.
