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...

Abstract

The invention discloses a self-adaptive radiotherapy method based on image processing, and particularly relates to the technical field of image processing. The method mainly comprises the steps of obtaining a tissue density image of a target tissue in an initial state, and screening a region in a preset density range according to the tissue density image as a target region, setting an initial adjustment amount according to the density of the target region, according to the initial adjustment amount, adjusting the tissue density at the target region back, and starting to heat the tissue at the target region, in a heating state, calculating a current density influence parameter according to the real-time temperature, and calling a corresponding scaling coefficient from the contrast relation table according to the density influence parameter, and scaling the initial adjustment amount according to the scaling coefficient, and callback the tissue density at the target region according to the scaled adjustment amount. The scaling coefficient of the regulating variable is adjusted in real time according to the temperature field, the heat loss degree and the perfusion rate, so that the regulating variable can dynamically change according to the change of the activation energy of the biological tissue.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an adaptive radiotherapy method and 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...
