Title: Ultrasonic probe
Inventor: TAKEDA JUNICHI
IPC: H04R17/00
Filed: 2002-12-20
Abstract: <P>PROBLEM TO BE SOLVED: To enhance operability by reducing the width of the piezoelectric plate of an ultrasonic probe in the short axis direction thereof, and to improve the azimuth revolving power of short distance and the penetration of long distance.  <P>SOLUTION: The take-out opening of a ground electrode 2 formed on the ultrasonic wave radiating face side of the piezoelectric plate 1 of an ultrasonic probe is provided at an exposed part 7 of the end side face in the scanning direction and connected externally through a common ground line 11. Since the short axis effective opening width is equalized to the width of the piezoelectric plate 1 in the short axis direction, the width in the short axis direction can be shortened and the operability is enhanced. Since the short axis effective opening width of ultrasonic wave being radiated from the piezoelectric plate 1 is increased, a good ultrasonic tomographic image having reduced reflection noise is obtained even in case of scanning through a limited gap. When the ground electrode of a piezoelectric oscillator is divided in the short axis direction and switched selectively by means of a switch, an optimal beam can be formed depending on the measuring region by varying the short axis effective opening width. Consequently, the azimuth revolving power of short distance is enhanced and the penetration of long distance can be improved.  <P>COPYRIGHT: (C)2003,JPO
