Magnetic fluid detection device

摘要

A magnetic fluid detection device (1) for detecting a magnetic fluid staying in a body to be examined includes an exciting unit for generating an exciting magnetic field to excite a magnetic fluid staying in a subject, a coil (22) for detecting a local distortion in magnetic field distribution occurring due to the magnetic fluid excited with the exciting magnetic field generated by the exciting unit, and a control unit (4) for signal-processing an output from the coil and informing the resultant signal magnitude.
