    摘要: Radiofrequency ablation (RFA) technique has been widely used around the world as a minimally invasive treatments, particularly for primary and metastatic liver tumors, as well as tumors in kidneys, bones and skins. In practical, this technique by which deposition of electromagnetic energy is used to thermally heat tissues can cause dispersive ground pad site burns. However when electrode pad site burns for skin tumor treatments could also produce high temperatures at the edges or at the corner of the pads attached to the patients’ body. Skin burn at the ground pad has become a limiting factor for further increasing in ablation volume dimensions and generator power. The objective of the study is to investigate factors of leading ground pad burns and propose solutions via computer simulation in order to provide better healthcare for patients. As a result, larger ground pad may reduce high temperatures at edges or corners of the pad, however the corners and edges of the heating pad may increase tissue temperatures.
