Abstract
A low-cost modular liquid nitrogen low-temperature multi-nuclear magnetic resonance probe includes a Dewar, a pluggable coil and a front-end gain amplifier. The Dewar includes a cylindrical sandwich chamber, the center of the cylindrical sandwich chamber constitutes a room-temperature chamber, a sandwich of the cylindrical sandwich chamber is divided into a vacuum chamber and a liquid nitrogen chamber by a liquid nitrogen vessel wall, the vacuum chamber is located between the room-temperature chamber and the liquid nitrogen chamber, the pluggable coil and the front-end gain amplifier are provided in the vacuum chamber, the pluggable coil comprises a coil portion and a pluggable base, the coil portion is in pluggable connection with the pluggable base, and the pluggable coil is connected with the front-end gain amplifier. The probe realizes the transmission of radio frequency pulses and the reception of magnetic resonance signals, and is applicable to whole-body imaging of a small animal.
