High Temperature Superconductor Tape Rf Coil For Magnetic Resonance Imaging

Abstract

A Hts Rf Coil Is Disclosed Having At Least A Factor Of Three Improvement In The Snr Over A Comparable Copper Coil And At Least A Factor Of Six Improvement In Q Over A Comparable Copper Coil. A Commercially Available Hts Tape Is Formed Into A Loop. High-Q Capacitors Are Soldered Across The Loop Ends. The Silver Sheath Covering The Tape Is Removed Through Chemical Etching. The Coil Is Placed In A Holder For Mechanical Support And Protection And Covered With A Cover Having Through Holes Enabling The Coolant To Directly Contact The Hts Coil.
