Abstract

The heat field boundary displaying method for microwave interventional therapy of tumor includes the following steps: 1. measuring and calculating SAR distribution function of real-time 3D solidification heat field of single microwave antenna under different radiation power; 2. establishing mathematic model of heat field distribution under the action of over one microwave antenna based on the SAR distribution function; and 3. substituting the boundary temperature of the heat solidification region, the treating time and the tumor perfusing coefficient into the mathematic model of heat field distribution to find out the coordinate points meeting the requirement of the mathematic model and to find out the 3D display of the coordinate point set through software treatment. The present invention has continuous regulation of treating parameters, simple process, fast calculation speed and real-time display.

Description

technical field

[0001] The invention relates to a method for displaying the boundary of a microwave radiation thermal field, in particular to a method for displaying a boundary of a three-dimensional thermal field for interventional treatment of tumors with multiple microwave treatment needles. Background technique

[0002] Microwave interventional therapy for tumors is to puncture the microwave antenna (treatment needle) percutaneously into the lesion area of ​​the human body, use the microwave antenna tissue to generate microwaves, form a certain shape of thermal coagulation area in the local area irradiated by microwaves, and use high temperature to heat necrosis of the tumor. It is the most ideal treatment plan that the thermal coagulation zone just completely covers the tumor. If the boundary line of the thermal coagulation zone exceeds the outline of the tumor, the normal tissue cells in the human body will be damaged. If the thermal coagulation zone does not completely...
