Problems solved by technology

[0002] High-intensity focused ultrasound therapy technology is a practical clinical ultrasound therapy technology developed in recent years. So far there is no suitable method for measuring the focal area of ​​the focused sound field emitted by the high-intensity focused probe, which largely limits high-intensity focused ultrasound therapy. The development of intensity-focused ultrasound therapy technology, further research on the dosimetry of ultrasound therapy is also very limited

Abstract

An equipment for measuring the sound field in a focused region of high-intensity focused ultrasonic field is composed of a supporting frame, a sound-absorbing water tank, a data processor, a pressure-sensitive sensor able to directly measure the sound pressure of high-power high-intensity sound field, 3D movement regulator, 2D rotation regulator, and probe holder. Its advantages are high speed and accuracy and simple operation.

Description

Technical field: [0001] The invention relates to a sound field measuring device, in particular to a high-intensity focused ultrasonic sound field measuring device. The device mainly uses a pressure-sensitive sensor to measure the sound pressure of the ultrasound emitted by the high-intensity focused ultrasound transducer. The device is more practical and stable for the sound field measurement of the focus area of ​​the high-power, high-intensity focused ultrasonic transducer. Background technique: [0002] High-intensity focused ultrasound therapy technology is a practical clinical ultrasound therapy technology developed in recent years. So far, there is no suitable method for measuring the focal area of ​​the focused sound field emitted by the high-intensity focused probe, which largely limits high-intensity focused ultrasound therapy. The development of intensity-focused ultrasound therapy technology and further research on the dosimetry of ultrasound therapy are also ver...
