A real time Wall Monitoring System (WMS) is used on the WEST tokamak during C4 experimental campaign. The WMS uses wall surface temperatures from 6 fields of view Infrared viewing system. It extracts raw digital data selected areas, converts it to using calibration and write shared memory network being by Plasma Control (PCS). PCS feeds back actuators, namely injected power 5 antennae's lower h...

BACKGROUND Radiofrequency surgery is a method of utilizing high frequency (3.8 to 4MHz) radio wave energy to incise, excise, or coagulate tissues. Radiofrequency (RF) is a relatively new modality that is being used for ano-rectal surgeries with increasing frequency. As the RF energy is applied, frictional heating of tissues results, with cell death occurring at temperatures between 60 and 100 d...

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...

BACKGROUND Remote heating of metal located near a radiofrequency ablation source has been previously demonstrated. Therefore, ablation of cardiac tissue treated with metallic nanoparticles may improve local radiofrequency heating and lead to larger ablation lesions. We sought to evaluate the effect of magnetic nanoparticles on tissue sensitivity to radiofrequency energy. METHODS AND RESULTS A...

In the last decade, Radiofrequency (RF) energy has proven to be safe and highly efficacious for face and neck skin tightening, body contouring, and cellulite reduction. In contrast to first-generation Monopolar/Bipolar and "X -Polar" RF systems which use one RF generator connected to one or more skin electrodes, multisource radiofrequency devices use six independent RF generators allowing effic...

To the Editor: In recent years, the use of magnetic resonance imaging (MRI) has been increasing in patients with implanted devices, such as cardiac pacemakers and neurostimulators, which used to preclude the use of MRI owing to patient safety and device malfunction concerns.(1-6) In the past few years, however, more of these implant devices have become MR-compatible and can function properly du...

Introduction: Noninvasive radiofrequency (RF) tissue heating is frequently used for skin tightening and facial wrinkle reduction as alternative to invasive surgical procedures. The aim of this technique is to heat dermis and subcutaneous tissue in order to induce modifications in the collagen structure, which is then followed by formation of new collagen fibers and long-term tissue remodeling [...
