Document Type and Number:
WIPO Patent Application WO/2023/046121
Kind Code:
A1
Abstract:
A tuning device (100) for a receiving coil (L), a low-temperature probe, and a magnetic resonance device. The tuning device (100) comprises a fixed capacitor (C), a varactor assembly (120), and a control assembly (110); the fixed capacitor (C) and the coil (L) are connected in series; the varactor assembly (120) is connected in parallel to two ends of the fixed capacitor (C); the control assembly (110) is configured to tune the receiving coil (L) by controlling the capacitance value of the varactor assembly (120), the tuning comprising at least one of frequency tuning and impedance tuning.
