Title:
ULTRASOUND FOCUSING FIELD MODULATION SYSTEM BASED ON ARTIFICIAL ACOUSTIC STRUCTURE, AND MODULATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/108878
Kind Code:
A1
Abstract:
An ultrasound focusing field modulation system based on an artificial acoustic structure, and a modulation method thereof. The system comprises at least one ultrasound transducer (10), at least one artificial acoustic structure layer (20) formed on the surface of a matching layer of the ultrasound transducer (10), a parameter determination module (30) connected to the ultrasound transducer (10), and an electronic modulation module (40) connected to the parameter determination module (30). In the system, Fresnel diffraction is taken as a theoretical basis, an artificial acoustic structure theoretical model oriented to different ultrasound focusing field demands is established, artificial acoustic structures for different target stimulation demands are designed, and the field of the ultrasound transducer (10) is modulated by means of the artificial acoustic structures, so that precise and variable ultrasound field modulation can be realized, and the resolution and precision of deep brain ultrasound focusing can be improved.
