Insertable NMR coil probe

摘要

A nuclear magnetic resonance (NMR) imaging method and apparatus is disclosed. The apparatus is an insertable probe consisting of a handle portion and an insertable portion. The probe has a NMR signal receiver disposed within the insertable portion and a reception frequency tuner which may be connected to an actuator which extends outside the sample into which the probe has been inserted. The NMR method of this invention includes the steps of inserting a NMR probe at a preselected detection location in a cavity within a sample, placing the sample in an external magnetic field, applying a perturbation pulse to the sample, and using the probe to receive the NMR emissions from the sample.
