Magnetic Field Analysis of Lesion Localization via GMR Probe

摘要

Magnetic field is analysed to lesion localization via GMR probe in the paper. Magnetic liquid is used to human body non-trauma lesion localization. Magnetic fluid is sent to the lesion targeted drug. The detection circuitry is a Wheatstone bridge with a giant magnetoresistance (GMR) and a coil. The resistance of GMR changes in magnetic field, then it can pinpoint the location of magnetic fluid.
