Residual field suppression for magnetocardiography measurement inside a thin magnetically shielded room using bi-planar coil
文献摘要：
For a magnetocardiography(MCG)system inside a magnetically shielded room(MSR),the residual field should be further suppressed to obtain high-quality MCG signals.In this paper,a compensation system has been developed based on the bi-planar coil and the proportional-integral-derivative(PID)controller.The bi-planar coil,derived from the target-field theory and the Tikhonov regularization method,is utilized to generate magnetic field with high uniformity in the pre-defined target region.And the PID controller is introduced to provide dynamic compensation current for the coil,according to the residual field change monitored by a reference SQUID magnetometer.The measurement results show that the noise suppression ratio(NSR)can reach above 20 dB in the low-frequency range from 0.1 Hz to 50 Hz.The DC component and the fluctuation of the residual field in time-domain can be respectively suppressed to 0 pT and 4 pT,indicating that this proposed compensation method is useful for the MCG measurement.
