Ultrasonic diagnosis and treatment method and system

Abstract

The present invention discloses an ultrasonic diagnosis and treatment method and system. The system comprises a plurality of biological signal processing devices, an ultrasonic wave transmitting device and a central processing device. The biological signal processing devices calculate the difference between the biological signals of a positioning target before and after the excitation of difference frequency ultrasound, generates a first index change amount, and calculate the difference between the biological signals of a positioning target before the excitation of the difference frequency ultrasound and after ablation of differential frequency ultrasound stimulation, and generates a second index change amount. The central processing apparatus transmits corresponding instructions to the ultrasonic wave transmitting device based on a comparison result of the first index change amount and a first preset index change amount as well as a comparison result of the second index change amount and a second preset index change amount, wherein the instructions include a target positioning instruction and a difference frequency ultrasound stimulation instruction, the same frequency ultrasound ablation instruction or a difference frequency ultrasound ablation instruction to achieve the diagnosis of a positioning target and the evaluation of ablation effect for the integration and automation of diagnosis and treatment.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and more specifically, to an ultrasonic diagnosis and treatment method and system. Background technique [0002] High-intensity focused ultrasound (HIFU) is a non-invasive treatment technology based on the physical characteristics of ultrasound such as good targeting, convergence, and penetration. In vitro emission, through the skin and corresponding tissues, reaches the target area in the body to focus, forming a focus with extremely high energy density, and through biological effects such as thermal effects, cavitation effects, and mechanical effects, the tissue cells in the target area can be activated in a short period of time. Coagulation necrosis occurs with little or no damage to the tissue on the acoustic channel and around the target area, so as to achieve the purpose of non-invasive ablation or resection of diseased tissue. HIFU technology has been widely used in the tr...

Problems solved by technology

[0003] In the current treatment, the determination of the target tissue is mainly guided by imaging images. After the target area of ​​the target tissue is determined, the target point is selected according to the doctor's experience, and then the target point is directly ablated by HIFU technology, which has no corresponding effect on the ablation effect. In addition, the diagnosis of the target in the target area depends on the subjective judgment of the doctor, and there is blindness
