Patent number: 6551247Abstract: Disclosed is an ultrasonic probe of high performance and high quality. The ultrasonic probe comprises a high molecular material having a conductive layer and is disposed between a piezoelectric element and an acoustic matching layer. The high molecular material has an acoustic impedance substantially equal to that of the acoustic matching layer. The ultrasonic probe thus configured can be formed into a slim shape which is easy to operate without degrading the performance thereof, such as sensitivity or frequency characteristics or the like. The ultrasonic probe is structured so as not to cause an electrical problem due to breakage of wire even if the piezoelectric element is cracked by a mechanical impact or the like, and thus a high quality ultrasonic probe can be provided, and noise can be reduced.Type: GrantFiled: February 7, 2001Date of Patent: April 22, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Koetsu Saito, Yasushi Koishihara, Junichi Takeda, Hirokazu Fukase

Patent number: 6418084Abstract: An ultrasonic probe includes a piezoelectric element for transmitting and receiving ultrasonic waves and an acoustic lens provided on an ultrasonic transmission/reception side of the piezoelectric element. The acoustic lens is formed in an acoustic lens shape by vulcanization formation through addition of 2,5-dimethyl-2,5-di-t-butyl peroxy hexane as a vulcanizing agent to a composition prepared by addition of silica (SiO2) particles in an amount of 40 wt % to 50 wt % to silicone rubber with a dimethylpolysiloxane structure including vinyl groups. Thus, the ultrasonic transmission and reception sensitivity is improved and the degradation in frequency characteristics is diminished. Consequently, higher resolution of an ultrasonic image and higher sensitivity can be achieved.Type: GrantFiled: February 14, 2001Date of Patent: July 9, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Koetsu Saito, Hirokazu Fukase
