Abstract
A magnetism characteristic detection method, a magnetism characteristic detection apparatus, an imaging apparatus and an imaging method are provided, where magnetism detection and imaging are based on an integrated excitation field of a direct current (DC) magnetic field and an oscillation wave. The magnetism detection method includes the following steps. A DC magnetic field is selectively applied to an object. Further, an oscillation wave is provided to the object, where the oscillation wave is a sound wave or an ultrasound wave. Then, a magnetism characteristic variation of the object is detected.
