Here, a curing resin may be impregnated therein so as to form resin-impregnated-cured portions. Then, the lamination is cut in a direction crossing a lengthwise direction of the sintered piezoelectric thin wires, so that a piezocomposite is obtained. Cut surfaces may be ground. By so doing, it is possible to provide a highly reliable piezocomposite having a fine structure at low cost, and to provide an ultrasonic probe for ultrasonic diagnostic equipment, as well as ultrasonic diagnostic equipment using the same.

摘要： 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.

摘要： Disclosed is an ultrasonic probe using a compound piezoelectric material made of piezoelectric ceramic and organic polymer. On one principal plane of the compound piezoelectric material, electrodes and electric terminals conducting to these electrodes are formed, and these electrodes and electric terminals are divided into a plurality. On the other principal plane of the compound piezoelectric material, a common electrode is provided, and an acoustic matching layer is mounted on it either intact or divided in correspondence to the divided electrodes. By using part of the compound piezoelectric material as the electric terminal take-out portion, the mechanical strength of the electric terminal take-out portion can be improved, which is particularly preferable for the ultrasonic probe driven at high frequency.

摘要： In an ultrasonic imaging system echo signals representative of the amplitude of ultrasonic energy returning along a plurality of angularly spaced paths are sampled at a constant speed and stored into a buffer memory. At a speed inversely proportional to the cosine of the angle of said path with respect to a reference line the echo samples are read out of the buffer memory and written into a specified area of a graphic memory at a constant speed in the direction of the rows thereof and at a speed proportional to the tangent of the angle of the path with respect to the reference line in the direction of the columns thereof. At a constant speed echo samples are read out of the graphic memory in the directions of the rows and columns and applied to a monitor to be displayed in a raster scan field.

摘要： A laminated body is formed. The laminated body includes layers. One of the layers includes a piezoelectric array. The laminated body is engaged with both a pressing film and a curved member having a curved outer surface. A tension is exerted on the pressing film to press the laminated body against the curved outer surface of the curved member so that the laminated body is bent along the curved outer surface of the curved member. The use of the pressing film may be replaced by a process in which at least one of the layers is subjected to a tension to bend the laminated body.
