Experimental Study on the Effects of Branching Vessels on Temperature Distribution in Microwave Ablation Therapy

Theoretical work has shown that blood flow plays an important role in determining temperature profiles of heated tissues. And in the complex blood network, the construction of branching vessels is the most important. In this paper, an experimental study on the effects of branching vessels on temperature distribution was performed. The experiment was implemented in a muscle-equivalent microwave phantom instead of liver tissue, because they have similar electric characteristics. We investigated the effect on temperature distribution of different blood velocities, and provided a academic gist for compensatory measure in clinic.
