Abstract
This paper briefly reports the literature on Litz wires employed for MR coil design and their influence on coil performance. Successively four circular coils, tuned at frequencies in kHz and MHz ranges, were built by using wire and Litz wire conductors. Realized coils were tested and characterized by laboratory workbench in order to measure quality factors and to compare the performance of the different conductors typology. Our results are applicable in several situations as MR imaging in low field scanners, imaging of nuclear species at low fields, Overhauser systems and prepolarized NMR. Moreover, we believe Litz wire could be successfully employed in MRI/magnetic particle hyperthermia (MPH) systems.
