Abstract

An inductively coupled wireless radio frequency (RF) coil has been developed to improve the quality in the magnetic resonance imaging. The wireless coils of a Helmholtz type and a birdcage type were manufactured, and the resonance frequency was tuned at 64 MHz. Several magnetic resonance images were taken on a phantom and on a human knee with the RF coils. The signal to noise ratio (SNR) has been compared at the acquired images. The experimental results show that the SNR is improved with application of the inductive coupling between the RF coils.
