Abstract :
This paper presents a novel calibration system for measuring inhomogeneity of magnetic field of medical nuclear magnetic resonance. The misdiagnosis owing to inhomogeneous magnetic field was prevented by the greatest extent. By virtue of signal averaging technique, even weaker nuclear magnetic resonance signals were also extracted from the noise environment. The experiments showed that inhomogeneous magnetic field more or less existed in most of medical nuclear magnetic resonance.
