The work is devoted to the study of characteristics a low-temperature plasma high-frequency (HF) discharge (f=13.56 MHz) ignited between metallic and electrolytic electrodes at atmospheric pressure. Burning an RF in diffuse (volumetric) form observed interface media electrodes. Numerical calculations electric field strength distribution volumetric power density Joule heat release before breakdo...

PURPOSE We assessed the value of dose-volumetric parameters predicting rectosigmoid mucosal changes (RMC) and late rectosigmoid complications (LRC). METHODS Between January 2004 and February 2006, 77 patients with stage IB-IIIB cervical cancer underwent external beam radiotherapy and computed tomography (CT)-based intracavitary irradiation. Total dose to the rectal point and several dose-volu...

The possibility of volumetric phase recording based on photo-oxidation the side anthracene groups a new polymer with glass transition temperature ~338 K by oxygen that enters layer across boundary atmospheric medium, was established experimentally. Volumetric holographic gratings maximum diffraction efficiency 2.5–9.5% were recorded radiation from He–Ne laser (λ = 633 nm) in layers 5–20-μm thic...

The Agility multileaf collimator (Elekta AB, Stockholm, Sweden) has 160 leaves of projected width 0.5 cm at the isocenter, with maximum leaf speed 3.5 cms-1. These characteristics promise to facilitate fast and accurate delivery of radiotherapy, particularly volumetric-modulated arc therapy (VMAT). The aim of this study is therefore to create a beam model for the Pinnacle3 treatment planning sy...

Hepatic lobar atrophy-hypertrophy complex formation is an uncommonly reported sequella of hepatic arterial embolotherapy procedures. Whereas radiation-induced hepatic lobar ablation has been described after intra-arterial therapy with yttrium-90 microspheres, this phenomenon has not been reported after transcatheter arterial chemoembolization. Here, we report a case of prominent hepatic lobar a...
