Figures

Image of FIG. 1.
FIG. 1.

Matching and signal pick-up coils with variable tuning trimmer capacitor C1. Adjusting the capacitor C1, the imaginary part in Zin will be cancelled out of the resonant frequency.

Image of FIG. 2.
FIG. 2.

The 3T system setup of the phantom experiment, where the matching and signal pick-up coil with a tuning variable capacitance was put in the middle of the HTS tape coil and the phantom.

FIG. 3.

Experiment setup to measure the QF.

FIG. 4.

Coronal phantom images and mesh images comparison by Bruker fast spin echo sequence. The background noise of mesh image acquired from the HTS coil is significantly lower than that of the home-made copper coil. (a) Phantom image acquired from the home-made copper coil with . (b) Phantom image acquired from the HTS coil with . (c) Photograph of a 10 cm diameter spherical phantom filled with 10 mM . (d) Mesh image acquired from home-made copper coil. (e) Mesh image acquired from HTS coil.

FIG. 5.

Plots of intensities along the horizontal axis extracted from phantom images, in which the dash, solid curves denote the HTS in 77 K and home-made copper coil at room temperature, respectively.
