Abstract
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 and the box were filled with the same tissue, discrepancy to results of the two-tissue setup was up to 280%.
AI evidence extraction
Structured fields below were generated from the paper’s abstract and metadata to make the evidence easier to inspect. Automated extraction may be incomplete or incorrect; verify important details against the original paper.
Main findings
RF-induced power deposition generated by insulated leads depended substantially on the electrical properties of two surrounding tissues. When both surrounding regions were modeled as the same tissue (single-tissue setup), results differed from the two-tissue setup by up to 280%.
Outcomes measured
- RF-induced power deposition (p) near insulated leads
- Dependence of lead electromagnetic models on surrounding tissue electrical properties
Limitations
- Frequency and exposure parameters were not reported in the abstract.
- No biological/clinical outcomes were described; focus was on modeling/power deposition.
- Sample size and whether results are experimental or purely computational are not specified in the abstract.
