Abstract
The application discloses an acoustic impedance matching material and a preparation method and application thereof. The acoustic impedance matching material comprises a plurality of impedance layers arranged in a stacking mode, and the impedance layers are arranged in sequence in a stacking direction according to an exponential impedance variation relationship. Each impedance layer comprises a liquid matrix material and a filler in the liquid matrix material. The acoustic impedance matching material can make the ultrasonic wave maintain sufficient energy and a wide bandwidth to enter the intracranial cavity, has high imaging resolution and high focusing intensity, and can guarantee efficient transcranial ultrasonic energy transmission, and is further used for brain disease observation and treatment.
