Receiver coils using High-Temperature Superconducting (HTS) materials are able to achieve higher quality factor (Q-factor) over conventional copper coils, thus higher signal-to-noise ratio (SNR) or shorter imaging time. Substantial SNR improvements were introduced by surface coils made of expensive HTS thin film. A 5-inch HTS coil using silver-alloy sheathed Bi-2223 tape was first developed, where lower cost, easier fabrication and more flexible coil configuration can be achieved. In our work, an HTS volume coil for in-vivo mice imaging in low-field MRI system is first demonstrated.
