An SV-GMR Needle Sensor-Based Estimation of Volume Density of Magnetic Fluid inside Human Body

الملخص EN

A spin-valve giant magneto-resistive (SV-GMR) sensor of needle-type configuration is reported to estimate the volume density of magnetic fluid inside human body.

The magnetic fluid is usually injected into human body to kill cancerous cell using hyperthermia-based treatment.

To control the heat treatment, a good knowledge of temperature is very much essential.

The SV-GMR-based needle-type sensor is used to measure the magnetic flux density of the magnetic fluid inside the human body from which the temperature is estimated.

The needle-type sensor provides a semi-invasive approach of temperature determination.
