Atrial fibrillation and heart failure often coexist in patients with advanced heart failure symptoms. The result, in addition to a significant impact on quality of life, is an increase in the risk of ...
When conducting laser ablation of biological tissue, a tomography of the tissue surface is necessary to measure the crater shape and crater depth, and observe damage to the surrounding tissue. In thi...
In surgery, failure of ablation is fatal to patients, and the operation is difficult for residents to learn. Our study aims to provide a VR-based training environment for ablation. This paper presents...
For tumor ablation procedures typically lasting at least 5 min, this study shows that modeling the heat sink effect of large vessels by applying constant h as a boundary condition will yield precise r...
The best-fit least square functions were always obtained with quadratic curves where volume and diameters of coagulation were maximum for a PD of 2 mm. A thirty per cent increase in volume coagulation...
Radiofrequency ablation is an interventional technique that in recent years has come to be employed in very different medical fields, such as the elimination of cardiac arrhythmias or the destruction ...
Background An axisymmetric finite element method (FEM) model was employed to demonstrate important techniques used in the design of antennas for hepatic microwave ablation (MWA). To effectively treat...
We present results of a temperature controlled 3-D FEM model of a RITA model 30 electrode. The control software effectively controlled applied voltage in the FEM model to obtain, and keep electrodes a...
Both the computer model and the in vitro study confirmed that preferential heating of the tumour during RFA exists in breast tissue. However, the observed preferential heating in the in vitro studies ...
The data demonstrate the size of thermal lesions is grossly overestimated when calculated using traditional temperature isocontours of 42°C and 47°C. The computational model results predicted lesion d...
The data demonstrate that significant errors are generated when constant electrical conductivity is assumed in coupled electrical-heat transfer problems that operate at high temperatures. These errors...
