Reagent fixed-point release method and system based on ultrasonic microbubble radiography

Abstract

The invention discloses a reagent fixed-point release method based on ultrasonic microbubble radiography, which relates to the technical field of image processing, and comprises the following steps: performing tissue injection containing specific reagent microbubbles according to the type of abnormal tissues; the supermolecule image of the whole tissue is obtained through high-frequency ultrasonic waves; according to the supramolecular imaging, using the convolutional neural network trained by the image corresponding to the abnormal tissue to perform identification determination and region extraction of the abnormal tissue; focusing of low-frequency ultrasonic waves is carried out according to the area where the abnormal tissue is located; microbubbles in the area where the abnormal tissue is located are burst through the focused low-frequency ultrasonic waves, and specific reagents carried by the microbubbles are released. According to the method, after the supramolecular image is obtained through the high-frequency ultrasonic waves, the edge of the abnormal tissue is defined through the convolutional neural network model, and the ultrasonic waves are changed into low frequency to perform fixed-point microbubble burst control, so that abnormal tissue structure screening and repairing are combined, and the variation degree of the abnormal tissue can be judged.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for point-to-point release of reagents based on ultrasonic microbubble contrast. Background technique [0002] In ultrasound molecular imaging technology, contrast microbubbles can significantly enhance the backscattering ability of ultrasound, and are usually used in ultrasound imaging to enhance the grayscale imaging of tissue structures, thereby increasing the image accuracy, clarity, and resolution of ultrasound imaging. rate, improving the graphic quality of ultrasound imaging. [0003] With the development of ultrasound technology, the application range of ultrasound has been practiced in more aspects. Among them, using ultrasound to determine and repair (or eliminate) abnormal tissue structures is a new application direction of ultrasound. Specifically, by attaching specific reagents (particulate substances that can physically or chemically r...

Problems solved by technology

[0004] At present, the application of ultrasound in the market is mostly limited to the acquisition of tissue internal structure imaging, and the fixed-point controlled release of microbubbles loaded with repairing reagents is still in a state of inefficiency. , controlled release amount, lack of effective control, mostly in a "random" burst state, which is very likely to cause damage to the normal tissue structure
