Synopsis

Keywords: RF Arrays & Systems, RF Arrays & Systems, Knee, MRI, wireless coil, SNR, Tx/Rx, RF coil.

Motivation: The conventional Tx/Rx knee coil optimizes transmission and reception using a complex dual-layer structure with multiple components, requiring local transmit power and a limited diameter.

Goal(s): Developing a knee coil for that offers superior performance, patient-comfort, and affordable, without the need for a local transmit connection.

Approach: Design a wireless Tx/Rx knee coil incorporating system body coil in transmit phase and a flex phased array during receive phase, evaluating its performance against the flex phased array alone using phantom and in vivo imaging.

Results: Enhanced SNR is achieved when compared to a 13-channel flexible phased array, effectively eliminating wrap-around artifacts in knee image.

Impact: The advancement of inductive RF resonator technology with a wireless birdcage resonator incorporating a Figure-of-Eight (Fo8) conductor design is aiming to achieve cost-effective and improved performance for knee MRI which improves the way of designing MRI coils and their applications
