Abstract

An ultrahigh resolution magnetic resonance imaging method and apparatus, the method comprises the following steps of: placing a test sample within an action range of a magnetic gradient source and a nano-scale superconducting quantum interference device, applying a static magnetic field on the test sample by a static magnetic source, and applying a nuclear magnetic resonance radio-frequency pulse on the test sample by a radio-frequency source to excite the test sample to cause nuclear magnetic resonance; directly coupling the nano-scale superconducting quantum interference device with the test sample to detect nuclear magnetic resonance spectrum signals generated by the test sample; establishing an image of the test sample according to the detected nuclear magnetic resonance spectrum signals and space distribution information of gradient magnetic fields generated by the magnetic gradient source.
