Non-invasive Temperature Monitoring Using Small Coils During Radio-frequency Heating.

Radio Frequency Heating Coils for Shock Wave Experiments

Radio-frequency eddy current heating of metallic samples in shock wave, ultrasonic and diamond anvil apparatus provides a methodology for obtaining hot samples or hot metallic gaskets (containing a sample) and yet not heating the entire target, ultrasonic assembly or diamond cell. Analysis of a previous design of a radio-frequency (~0.5 MHz) coil demonstrated that the center of 13 mm diameter s...

Low Invasive Temperature Monitoring Method for Hyperthermia Using Induction Heating

In this study, we develop a local heating method and monitoring method for hyperthermia using the Ferromagnetic Implant with Low Curie Temperature (FILCT) under a high frequency magnetic field. We describe the experimental setup and in vitro experimental results.

Sterilization of Foodstuffs Using Radio Frequency Heating

A study was conducted with a pilot-scale sterilization system based on 27-MHz radio frequency (RF) energy to investigate the effectiveness in shortening process time and in improving quality for foods sealed in 6pound military-ration polymeric trays. Chemical marker M-1 was used to evaluate heating uniformity in 20% whey protein gels as a model food, and macaroni and cheese was processed to ass...

Non-invasive ultrasound-based temperature imaging for monitoring radiofrequency heating-phantom results.

Minimally invasive therapies (such as radiofrequency ablation) are becoming more commonly used in the United States for the treatment of hepatocellular carcinomas and liver metastases. Unfortunately, these procedures suffer from high recurrence rates of hepatocellular carcinoma ( approximately 34-55%) or metastases following ablation therapy. The ability to perform real-time temperature imaging...
