Problems solved by technology

Since there is no corresponding relationship between the gray value difference and the actual tissue damage, in clinical treatment, the operating doctor needs to have strong experience, that is, it is highly dependent on the doctor's clinical experience, which is not conducive to high-intensity focused ultrasound. Promotion of technology
[0007] In summary, it is very difficult and inaccurate to directly judge whether coagulation necrosis occurs from the gray scale changes of ultrasound images of B-ultrasound equipment. A therapeutic device for effectively judging whether coagulation necrosis occurs in the target area

Embodiment Construction

[0031] The content of the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0032] The inventor found through research that in order to accurately judge the area and degree of coagulation necrosis, it is necessary to use stable ultrasound images for judgment after treatment, and the ultrasound images after stabilization are stronger than the echoes before treatment, mainly due to two reasons, one is The boundary reflection formed by the denatured tissue and the surrounding tissue, and the second is the enhanced echo generated by the change of tiny particles in the tissue degeneration area. When the boundary acoustic impedance formed by the denatured tissue and the surrounding tissue is small, the echo enhancement produced by the boundary is actually very weak. In addition, the change of tiny particles in the tissue degeneration area may either enhance the echo or reduce the echo. , at the same time,...

Abstract

The invention relates to a high-intensity focused ultrasound treatment device for judging whether a treatment effect is achieved or not by using speckle distribution changes in a treatment target area image. Speckle centers and organization edges of an acoustic image before treatment and a real-time acoustic image are extracted by a registration module in the device, the registration of the images before and after the treatment is realized, and indexes of the speckle distribution changes before and after the treatment of a target area are calculated by matched images to judge whether coagulative necrosis is generated at lesion or not. The device can greatly improve the precision rate for judging whether the coagulative necrosis is generated in the target area or not and is not influenced by human factors.

Description

technical field [0001] The invention relates to the technical field of high-intensity focused ultrasound treatment, in particular to a high-intensity focused ultrasound treatment device using ultrasound for treatment, and in particular to a high-intensity focused ultrasound treatment device that uses changes in the speckle distribution in the image of a treatment target area to determine whether a therapeutic effect has been achieved. Ultrasound therapy device. Background technique [0002] Medical research has found that the heat resistance of tumor cells is worse than that of normal cells. In a temperature environment above 42.5°C, tumor cells die within 30 minutes, while normal cells are slightly damaged and reversible. Based on this characteristic of tumor cells, the high-intensity focused ultrasound tumor therapy system uses ultrasound as the energy source, uses its penetrability and focusability, and couples the ultrasound with low average sound intensity emitted by th...
