Abstract:
1. An apparatus for the detection, measurement, or location of one or more predetermined types of cancer cells or biologic substances in vivo, comprising: (a) a magnetizing subsystem, configured to magnetize nanoparticles that are bound to one or more predetermined types of cancer cells or biologic substances in a patient; and (b) a sensor subsystem, configured to detect a residual magnetic field in a region of the patient during a time after the net magnetic moments of nanoparticles not bound to cancer cells or biologic substances have decayed and before magnetic moments of nanoparticles bound cancer cells or biologic substances have decayed, and (c) an analysis subsystem configured to analyze the residual magnetic field to detect, measure, or locate the one or more predetermined types of cancer cells or biologic substances in a patient.
