Simulation of tissue heating by magnetic fluid hyperthermia

Objective: Magnetic fluid hyperthermia is a technique in which thermal energy is generated by magnetic nanoparticles (MNPs) that are excited by an alternating magnetic field (AC field). During hyperthermia, in-vivo monitoring of elevation of temperature relies on invasive insertion of conventional thermometers, or employment of thermo-sensitive cameras that lack high precision....

Electric discharge during electrosurgery

Electric discharge utilized for electrosurgery is studied by means of a recently developed method for the diagnostics of small-size atmospheric plasma objects based on Rayleigh scattering of microwaves on the plasma volume. Evolution of the plasma parameters in the near-electrode sheaths and in the positive column is measured and analyzed. It is found that the electrosurgical system produces a ...

Fundamentals of electrosurgery.

Electrosurgery uses electricity to remove tissue, coagulate bleeding, or destroy tumors. Modern units, first developed for application in neurosurgery, are now available in office models that are most commonly used by the family physician for cutaneous surgery. Electrosurgery can accomplish cutting, coagulation, desiccation, and fulguration. Electrosurgical equipment for the office is relativel...
