Instead, MRI requires the use of a relatively safe radio frequency (RF) signal, which can however be problematic for patients with implantable medical devices. The RF induced heating on twenty-four titanium rods with different diameters, coatings, and lengths, were placed, within a phantom of gelled saline, inside a 1.5 T, 64 MHz test system for 15 minutes, one-by-one. Thermal simulations were carried out in SEMCAD X. The partially insulated rods experienced the highest increase in temperature out of all the coating configurations. Also, the titanium rods that were closer to the length of a half-wavelength dipole antenna in general experienced a higher increase in temperature. Finally, the thinner rods experienced a higher increase in temperature than the thicker rods.application/pdfengThe author of this work is the copyright owner.
