Abstract
We have built and tested a thin-film high temperature superconducting (HTS) surface coil for MRI at 0.064T. When placed as close as possible to a conductive sample, the 6.7-cm outer diameter HTS coil had a measured signal-to-noise ratio (SNR) 1.8 times higher than a room temperature copper coil of similar size and location. Our results predict that in some cases, SNR gains of about a factor of 2 can be attained in low-field MRI systems by substituting HTS surface coils for copper coils.
