Abstract

The application discloses a microwave ablation heat field simulation method based on a Bezier curve, and belongs to the technical field of medical image processing and simulation. The method first collects microwave ablation data of an ex vivo test tissue, obtains a function curve of the long diameter and the short diameter of an ablation area changing with an ablation temperature based on the collected data, and generates an ablation heat field model by using a Bezier curve; ablation operation planning simulation is carried out based on the parameters of the established Bezier ablation heat field model; finally, the established Bezier curve ablation model is embedded in simulation software, and operation simulation is carried out by inputting operation scheme parameters. The simulated microwave ablation heat field of the application is more consistent with the actual ablation effect, the temperature field distribution in virtual tissue and the virtual ablation area range are obtained by simulation model calculation; the method reduces the calculation complexity of the model in the simulation software, and can be used for describing the radio frequency ablation heat field or the cryoablation low-temperature ablation field in addition to the simulation microwave ablation heat field.
