1 Four parts are included : acoustic lens, mechanics I electronic circuitsand microcomputer system.
2 It has put forward a imaging method of acoustic lens using photoacoustic signal and according to the Kirchhoff diffraction theory we deduced pulse response of acoustic lens.
3 The acoustic lens focus system has many strong points, such as: ease of operation, structure simple, diverse shape and cheap of sound material and widely applied in the clinical medicine.
4 Dubbed an acoustic lens, the device could also be used to create near photo-quality images of internal organs that surpass the resolution of modern ultrasounds.
5 Waveguide to be fitted - the first acoustic lens system ever fitted to a Dual Concentric.
6 As an imaging tool, the acoustic lens beats ultrasound imaging because the sound pulses can be focused much more tightly and can be easily repositioned.
7 Designed acoustic imaging system, it is demonstrated that using acoustic lens imaging is feasible through measuring these sound fields distributing of single dot body and three dots body.
8 But such applications are still a ways off, she said, as the acoustic lens has not yet been tested on cells or living animals.
9 When a sound wave strikes the spheres at one end of the acoustic lens,(www.Sentencedict.com) the sound gets converted into a type of shock wave known as a solitary wave.
10 The toy inspired study co-author Chiara Daraio to invent the acoustic lens, which uses 0.95-centimeter stainless steel spheres aligned in parallel chains.
11 Acoustics, the geometric space figure that is made up of the acoustic foci of an acoustic lens, mirror, or other acoustic optical system and is the acoustic counterpart of an extended source of sound.
12 Results and Conclusions:Our simulations show that in order to improve the focal shape, the outer diameter of the annulus must be as large but the radius of acoustic lens must be as small as possible.
13 It was shown that using polystyrene as wedge material, high polymer as transducer material and curved wedge as an acoustic lens was the key point of application effectiveness for phased array system.
14 Many ultrasonic treatment systems produced by The Chongqing HIFU Company are acoustic lens focus system.
15 Now, focus transducers have three kinds of types: Focus transducer, acoustic lens, phased array focusing system.
16 By using complex amplitude to describe sound field distributing, acoustic lens pulse response is deduced in theory, and function imaging of biological tissue is obtained.
