    摘要: New method of cooling of MRI coil and resonators is disclosed and described. MRI coil designs showed in the disclosure are based solely on the use of copper tube elements filled with liquid nitrogen. Inside the conducting tubes at rf frequency there is no rf electric field, thus the liquid nitrogen presence inside such coils will not have any influence on MRI coil dielectric losses and on the resonant frequency modulation. Liquid nitrogen cooled coils, when in the coil noise regime, demonstrate 2-3 gain of signal-to-noise ratio comparing with room temperature equivalent coils. Methods for making and using both superconducting and normal metal MRI coils and/or arrays in such configurations are also disclosed.
