title: [Improvement of the surface coil of weida low magnetic field imaging system].
abstract: By Replacing Litg wire with copper tube (phi 6 mm, thickness 0.7 mm), we increase the WEIDA low magnetic field imaging system surface coil's signal to noise ratio from 12 to 23, quality factor from 60 to 136, and reduce bandwidth from 50 kHz to 30 kHz.
