OBJECTIVE Artifacts from gas bubble formation during radio frequency ablation along with the poor intrinsic contrast between normal and treated regions (zone of necrosis) are considerable problems for the visualization of the necrotic region on conventional sonography. Sonographic elastography is very effective for visualizing the zone of necrosis, but it uses the same echo signals to estimate ...
background chronic sacroiliac (si) joint pain constitutes 16% to 30% of the total prevalence of chronic low back pain, which is commonly unilateral. apart from conservative management, various interventional pain management procedures have been reported. intraarticular deposteroid injection has been described as the most evidence-based, but different various radio frequency (rf) procedures have...
In this article, a method is proposed for analysing the thermovision-based video data that characterize the dynamics of temperature anisotropy of the heart tissue in a spatial domain. Many cardiac rhythm disturbances at present time are treated by applying destructive energy sources. One of the most common source and the related methodology is to use radio-frequency ablation procedure. However,...
extremely low frequency (elf) and radio frequency (rf) electromagnetic field may affect biological systems by raising generation free radicals by decline activities of glutathione peroxidase dismutase or increase in the lifetime of free radicals with inhibited pretreatment of cells antioxidant like that alpha tocopherol. elf and rf electromagnetic field maycan damaged dna with raising level ...
