Problems solved by technology

Generally, malignant tissue has specific structural density characteristics compared with normal tissue in biological tissue, so the existing methods for eliminating malignant tissue in biological tissue mainly determine the malignant tissue area based on the structural density image of biological tissue range, and then ablate it with radioactive rays, so that the structural density of the target area can return to a normal level, thereby making it harmless

Embodiment 1

[0040] Due to the fact that malignant tissues (deteriorated biological tissues) have very different biological structural properties compared with normal biological tissues, and the tissue density of malignant tissues also has great differences compared with normal biological tissues , generally speaking, malignant tissue is in a state of aggregation and hardening, with high tissue density, and specific malignant tissue has a specific range of tissue density. Therefore, the characteristic of different structural densities of biological tissues can be used to screen the target area to be eliminated according to the specific density range of malignant tissues.

[0041] In conventional methods, the elimination method of malignant tissue in biological tissue is to divide the target area based on the above-mentioned characteristics of different tissue densities, and then ablate the malignant tissue by irradiation of radioactive rays. However, the conventional method does not adjust...

Embodiment 2

[0065] In order to better understand the technical content of the present invention, this embodiment illustrates the present invention in the form of a system structure, such as figure 2 As shown, an adaptive radiotherapy system based on image processing, including:

[0066] A target screening module, configured to acquire a tissue density image of the target tissue in an initial state, and select an area within a preset density range as the target area according to the tissue density image;

[0067] The initial value setting module is used to set the initial adjustment amount according to the density of the target area, and scale the initial adjustment amount according to the scaling factor;

[0068] A density stabilization module, configured to call back the tissue density at the target area according to the initial adjustment amount or the scaled initial adjustment amount, and heat the tissue at the target area during the callback process;

[0069] The coefficient retriev...

Abstract

The invention discloses an adaptive radiotherapy method based on image processing, specifically relates to the technical field of image processing, and mainly includes the steps of: acquiring a tissue density image in an initial state of a target tissue, and screening out tissue density images within a preset density range according to the tissue density image The area is used as the target area; the initial adjustment amount is set according to the density of the target area; the tissue density at the target area is called back according to the initial adjustment amount, and the tissue at the target area is started to be heated; in the heating state, the current density influencing parameters are calculated according to the real-time temperature , and the corresponding scaling factor is retrieved from the comparison table according to the density-affecting parameter; the initial adjustment amount is scaled according to the scaling factor, and the tissue density at the target area is recalled according to the adjusted adjustment amount after scaling. The invention adjusts the scaling coefficient of the adjustment amount in real time according to the temperature field, the degree of heat loss and the perfusion rate, so that the adjustment amount can be dynamically changed according to the change of the activation energy of the biological tissue.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an adaptive radiotherapy system based on image processing. Background technique [0002] In modern science, the research on biological tissues has become more and more in-depth, especially the research on the harmless treatment of malignant biological tissues has become extremely hot. Generally, malignant tissue has specific structural density characteristics compared with normal tissue in biological tissue, so the existing methods for eliminating malignant tissue in biological tissue mainly determine the malignant tissue area based on the structural density image of biological tissue range, and then ablate it with radioactive rays, so that the structural density of the target area can return to the normal level, thus making it harmless. However, the structural density of malignant tissue is in a state of dynamic change under radiation irradiation, so the radiation dose...
