Magnetic Field Sensors in Medical Diagnostics

Magnetic field sensors are considered promising in medical diagnostics. They are grouped into two types: type I – operating at room temperature; type II – requiring cryogenic cooling. It is noted that among type I sensors, laser-pumped atomic magnetometers are suitable, and among type II – SQUIDs (Superconducting Quantum Interference Devices). Also particularly promising are combined sensors consisting of a superconducting film with a nanostructured active band serving as a magnetic field hub and a structure with magnetoresistance as a magnetically sensitive element. © 2015, Springer Science+Business Media New York.
