Research Abstract

Acoustic lens has the possibility of improvement of acoustic characteristic of transducer not only in underwater application but also in medical application. The authors researched about the development of suitable acoustic designing method for catheter ultrasonic lens. A large acoustic lens composed of three-elements was firstly fabricated for underwater application. Specified acoustic lenses were basically designed by commercial available optical lens designing program. A 2D or 3D Finite Differential Time Domain (FDTD) method was used for wave-theoretical verification of acoustic characteristic of lenses in advance of fabrication. We can obtain fine images in water. In the second phase, the single midsize lens of 40mm whose scale factor was 10 was fabricated for catheter probe. The acoustic property was measured not only on normal incidence but also on oblique incidence. Calculated results agreed well with experimental results. We could obtain the acknowledges about lens designing method for catheter ultrasonic probe lens.
