Magnetic field image acquisition apparatus and method based on resonant structure

A magnetic field image acquisition method based on a resonant structure, comprising:

• generating a primary magnetic field through a transmitting coil;
• generating a secondary magnetic field through a resonance coil excited by the primary magnetic field;
• and
• generating a magnetic field image by detecting the magnetic fields generated by the transmitting coil and the resonance coil,
• wherein the transmitting coil and the resonance coil are designed to resonate at an identical operating frequency.

A magnetic field image acquisition apparatus based on a resonant structure, comprising:

• a transmitting coil configured to generate a primary magnetic field;
• a resonance coil excited by the primary magnetic field to form a secondary magnetic field;
• a magnetic field receiver that is a loop-shaped sensor array configured to detect the magnetic fields;
• and
• a magnetic field image signal processing unit configured to acquire a magnetic field image based on magnitudes and phases of magnetic field signals at respective points of the detected magnetic fields in a space,
• wherein the transmitting coil and the resonance coil are designed to resonate at an identical operating frequency.
