Attempt for determination the power absorption of nanomagnetic materials by reflectometry

摘要

Nanomagnetic hyperthermia is intensively studied with the prospect of cancer therapy. A major challenge is to determine the heat absorbed during in vivo conditions and conventional methods are either invasive or inaccurate. We present a method which yields directly the heat absorbed during hyperthermia: it is based on accurately measuring the quality factor change of a resonant radiofrequency (RF) circuit which is employed for the irradiation.
