ablation antenna has a high local temperature and is strongly destructive to surgical placement areas, which are usually covered with vessels, nerves, and other vital organs [10]. For these reasons, thermal ablation faces the risks of tissue necrosis, vascular rupture, and nerve damage. Therefore, scientific, and effective thermal ablation treatment is a very professional challenge for operating doctors. A standard method is to obtain temperature data through clinical thermal ablation, and then the temperature change law of biological tissue is analyzed and summarized [11; 12]. Many researchers have conducted thermal ablation experiments, such as [PERSON] et al. [13], which concluded radiofrequency ablation (RFA) temperature distribution in patients with malignant biliary strictures. To reduce the related complications, they designed a new RFA with automatic temperature control. Finally, they evaluated practicality in treating patients with malignant biliary strictures through clinical manifestations of 30 patients. [PERSON] et al. [14] performed microwave ablation (MWA) on the bovine femur and tibia to obtain temperature trends during MWA. They designed 40 thermometric points inserted into bone at a specific distance to explore a multi-point temperature study of bone structure. [PERSON] et al. [15] summarized the relevant research on lumen esophageal temperature measurement in catheter ablation surgery for atrial fibrillation. They compared the incidence of esophageal thermal damage and explored factors that may be associated with increased injury risk. Although clinical experiments can reproduce real surgical scenes and accurately match temperature changes in actual ablation operations, they can only obtain temperature changes in a limited range. Operating doctors rely on ultrasound images to observe tissue deformation. Therefore, it is impossible to establish an intuitive understanding of heat transfer and prediction. Numerical study has become an important research method in recent years [16; 17]. [PERSON] et al. [18] constructed a nonlinear segmented model of blood perfusion to construct a heterogeneous 3D numerical breast model and explore RFA effect on breast tumors with different density levels. They embedded 1.5 cm spherical tumors in different positions to represent early tumors. A proportional integral derivative (PID) controller was used to perform temperature control. Additionally, they combined coupled electric field distribution, Pennes photothermal and the first-order Arrhenius rate equation to perform thermoelectric analysis. [PERSON] et al. [19] established a finite element model using coupled electromagnetic fields and biological heat transfer equations. Compared with conventional microwaves (915 MHz, 2450 MHz), they evaluated the impact of high-frequency microwaves (6 GHz and 18 GHz) on liver cancer treatment. Damage area, temperature rise and characteristics distribution of biological tissue composed of liver and tumor were analyzed, which may represent the reality of cancer treatment. [PERSON] et al. [20] designed a new coaxial multi-slot antenna based on theoretical simulation to solve over-treatment status of existing coaxial slot antennas. They tested ablation process of tumors of different shapes and searched for the best slots number. [PERSON] et al. [21] proposed a computer model for kidney voltage distribution and temperature rise. The model further calculated the size of the RF lesion based on the dynamic process. Its instantaneous temperature and lesion size have been experimentally verified in an isolated porcine kidney model. It can be seen that numerical study is a simulation experiment that works in real scenarios. How to establish a relationship between a simulation experiment and fact, in order to verify model accuracy is a key issue that must be considered regarding numerical study. To explore the numerical study that was utilized for actual thermal ablation surgery, this work recorded the temperature change at a thermometric point in clinical MWA of biological tissues.
