| titleOfInvention | Switchable tuning matching device for high-uniformity nuclear magnetic resonance probe |
| abstract | The utility model relates to a harmonious matching device of changeable formula for high homogeneity nuclear magnetic resonance probe, including PCB board module, radio frequency coil module, PCB board module includes PCB board, low appearance value high performance radio frequency electric capacity, circuit shielding casing. The radio frequency coil module comprises a probe coil shielding shell, a Loop-gap coil, a PTFE cylinder, a coupling coil, a mechanical structure for fixing and adjusting the position of the coupling coil, a high-capacitance-value and high-performance radio frequency capacitor, a coaxial line with an SMA port, an arc aluminum sheet and a mechanical structure for fixing and adjusting the position of the aluminum sheet, wherein the Loop-gap coil can provide a uniform radio frequency field, but an inductive coupling structure is needed to average initial input current. The utility model discloses a changeable harmonious matching structure, the probe both can realize accurate tune and low noise through harmonious matching circuit, also can realize harmonious matching through mechanical structure's spatial position regulation, retrencies the structure greatly and shortens the tune time. The utility model discloses a harmonious matching device of this kind of switchable formula can make the tuning that the nuclear magnetic resonance probe satisfied under the different situation match the requirement. |
