[0093] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0094] The error extraction method of the magnetic particle detection system of the present invention uses two relatively independent magnetic particle detection methods, and obtains the relative difference through the comparison between the theoretical value and the measured value, and further completes the target value: induction coil inductance, induction coil voltage Or the error extraction of resonance frequency.
[0095] The error extraction method of the magnetic particle detection system of the present invention firstly obtains the magnetization M through the measured induced voltage signal, and uses the relationship between the magnetization M and the overall permeability μ of the induction coil and the induction coil L and the induction The relationship between the overall permeability μ of the coil is obtained by theoretical calculation of the theoret...
