Computed Tomography-Based Modeling of Water Vapor-Induced Changes in Permittivity During Microwave Ablation
One can imagine that boiling water has such different physical properties than drinking water. Microwave ablation, a minimally invasive cancer treatment modality, increases the temperature of tissues even higher than the boiling temperature of water to eradicate cancerous tissues. To achieve an accurate simulation for microwave ablation treatment planning, we need to consider all the changes that occur in tissue properties. In this study, we used computed tomography imaging to measure the amount of water vapor that accumulates in tissues during microwave ablation. We modeled tissue properties as a function of vapor content using mixture equations which possessed greater accuracy than existing models... Read more
