In Part I of this diptych, we outlined the theory and an analysis methodology for quantitative phase recovery from real-space distortions Fresnel images acquired in parallel mode transmission electron microscopy (TEM). that work, properties method, termed TEM-differential contrast (TEM-DPC), were highlighted through use simulated data. explore TEM-DPC technique with experimental cryo-TEM a thin...

The heating of deep visceral tumors with implanted electrodes and with self-regulating ferromagnetic thermoseeds was inves tigated. Clinical trials on six patients heated with implanted electrodes indicate that good local tumor control can be obtained by application of hyperthermia during a normal course of radio therapy. The heating method was found practical, and neither toxicity nor severe p...

PURPOSE To determine the MR compatibility of common dental retainer wires at 7 Tesla in terms of potential RF heating and magnetic susceptibility effects. METHODS Electromagnetic simulations and experimental results were compared for dental retainer wires placed in tissue-mimicking phantoms. Simulations were then performed for a human model with wire in place. Finally, image quality was asses...

This paper introduces a new method to control resonance frequency and output power of induction heating coil. Induction heating coil can be controlled by single phase sinusoidal pulse width modulation (SPWM) inverter .All electrical requirements beside magnetic permeability and resistivity variation for modeling induction heating coil have been considered to make simulations practical .Control ...

Induction heating is a famous technology and very filter, and a resonant inverter(8). V) this voltage enough to control of the IGBT circuit. 4IGBT. It is compared with the existing inverter topologies, half bridge and full bridge. The ordinary circuit of an AC-AC converter for induction heating typically includes a control rectifier By adjusting thewidth of the pulse that turns ON the IGBT. Abs...

A set of 2D steady state finite element numerical simulations of electromagnetic fields, eddy currents distribution and induction heating pattern has been done for different thicknesses of ametal workpiece. Comparison between the calculation results show the importance of workpiece thickness on induction heating process including electromagnetic field distribution, eddy currents pattern, heatin...

OBJECTIVES Infection of implants is a major problem in elective and trauma surgery. Heating is an effective way to reduce the bacterial load in food preparation, and studies on hyperthermia treatment for cancer have shown that it is possible to heat metal objects with pulsed electromagnetic fields selectively (PEMF), also known as induction heating. We therefore set out to answer the following ...
