Superconducting RF coils for clinical MR imaging at low field.

Rationale And Objectives: A number of recent reports in the MRI literature have established that substantial signal-to-noise ratio (SNR) gains can be achieved with small samples or low resonance frequencies, through the use of high-quality factor high-temperature superconducting (HTS) RF receive coils. We show the application of HTS coils to the imaging of human subjects with improved SNR compared with copper coils.

Materials And Methods: HTS coils were constructed from 7.
