Radiofrequency ablation (RFA) for liver cancer has increasingly been used over the past few years because RFA is minimally invasive treatment for patients. However, precise control of the formation of coagulation zones is difficult for operators due to inadequate imaging modalities. With this in mind, we have proposed a model-based robotic ablation system using numerical simulation to analyze temperature...
Radio frequency ablation (RFA), which is an important method for treating nonresectable and metastatic liver tumors, has increasingly been used over the past few years. On the positive side, RFA treatment is minimally invasive. On the negative side, the exact dimensions of the coagulated zone are not clearly visible in medical diagnostic images. A practical temperature distribution simulator is needed...
This paper presents a complete thermal analysis of a novel conformal surface thermometer design with directional sensitivity for real-time temperature monitoring during hyperthermia treatments of large superficial cancer. The thermal monitoring sheet (TMS) discussed in this paper consists of a 2-D array of fiberoptic sensors embedded between two layers of flexible, low-loss, and thermally conductive...
