Abstract

The invention provides a method for detecting a cavitation effect, and the method comprises the steps: controlling a first focused transducer to transmit detection signals to a focal region at a plurality of moments in an HIFU treatment process; acquiring a sound signal received by the first focused transducer at each moment; filtering the sound signal to obtain a signal of which the frequency is a first preset frequency at each moment, which comprising an echo signal corresponding to a detection signal generated by reflection of the focal region; according to the echo signal corresponding to the detection signal at each moment, generating echo feature information corresponding to each moment; and detecting whether a cavitation effect is generated in the focal region at least according to the echo feature information corresponding to each moment. The invention further provides a device for detecting the cavitation effect and ultrasonic treatment equipment.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of ultrasound therapy, and in particular, to a method and device for detecting cavitation effects, and ultrasound therapy equipment. Background technique [0002] At present, high-intensity focused ultrasound (HIFU) treatment technology mainly focuses ultrasound on a small focal area in the human body, and forms high-intensity, continuous ultrasonic energy on the tissue (lesional tissue, target tissue) corresponding to the focal area, thereby Transient high temperature effect, cavitation effect, mechanical effect and sonochemical effect are produced to rupture the cell membrane and nuclear membrane and coagulate protein, and then selectively cause coagulation necrosis of the tissue in the focal area, so that the tissue in the focal area Lose the ability of proliferation, invasion and metastasis, so as to achieve the effect of treatment. As a new technology for the treatment of tumors ...
