Title
Model and Simulation of Microwave Ablation with Single Antennas on Irregular Hepatic Cancerous Tissue.
Abstract
There is a lot of numerical simulation on microwave ablation which studied the models of the microwave antennas (MA) design and thermal-dielectric properties of tissues. However, few studies focused on the efficient and accurate treatment planning to configure MA in various kinds of irregular tumor, especially irregular hepatic cancerous tissue (IHCT). This work proposed a modelling approach to analyzing the heating performance and thermal lesion of microwave ablation model with different MA inserting directions, inserting depth rates and powers. The specific absorption rate and thermal lesion results showed that the long axis of irregular tissue could be the better MA inserting direction, along which microwave power could be sent to ablate more IHCT. The MA inserting depth rate influenced the power absorption rate and axial thermal lesion of the MA axis under different powers. The temperature field of 60 \(^{\circ }\)C expanded when power gave rise on, which were proposed to predict the thermal lesion zone of IHCT. The results simulated microwave ablation with single MA on IHCT, and thus, the method could also be applied to treatment situations where multiple MAs or more complicated operation are required under image-guided surgical navigation.
