Abstract:
The use of litz wire in their optimized frequency range can provide increased efficiency of high-frequency coils and lead to higher SNR in MR measurements. This work experimentally explores the added value of such a litz wire using equivalent solenoid coils in the range of 1 to 61 MHz. An improvement could be measured up to a frequency of 15 MHz, whereas the maximum effectiveness of the investigated wire was at 3 MHz. In addition, the SNR gain was validated in agreement on an 0.26 T MR system by comparing 1H FID signals.
