Mapping of a dual-frequency ultrasonic reactor was performed based on measurements of
local cavitation intensity at various horizontal and vertical planes in the reactor for single …

Background: The choice of gelatin as the phantom material is underpinned by several key
advantages it offers over other materials in the context of ultrasonic applications. Gelatin …

Given their advantage of suppressing grating lobes, randomly arranged linear arrays have
potential for use in ultrasonic treatment. The current work proposes a method based on …

This paper reports our recent design of an immersive acoustic tweezers capable of trapping
and holding large and heavy particles such as micro-particles up to 1 mm in diameter, as …

Background Utilizing spatially and temporally uniform tissue-mimicking phantoms for
ultrasonic applications can facilitate the characterization of beam distortion and attenuation …

An in-depth analysis on the beam directivity of ultrasonic phased arrays has been made to
solve the problems of low image quality and identification difficulties caused by a suboptimal …

声波是在弹性介质中传播的经典机械波. 当声波在物体表面发生反射, 折射, 散射等效应时,
会与物体产生动量与能量的交换. 这种交换在宏观上表现为声波对物体施加力的作用 …

This paper describes the modeling, design, fabrication and measurement of a focused
ultrasonic transducer with electrically controllability over the focal point location. Built on a …

This paper presents the design, simulation and fabrication process of a phase array
ultrasonic transducer based on 1mm-thick lead zirconate titanate (PZT) substrate with 128 …
