Description
本発明は、超音波探触子および超音波撮像装置に関する。 The present invention relates to an ultrasonic probe and an ultrasonic imaging apparatus.
そこで、本発明は、前記問題点に鑑みてなされたものであり、簡単な構造で超音波送受信の性能を向上させることができる超音波探触子および超音波撮像装置を提供することを目的とする。 Accordingly, the present invention, the has been made in view of the problems, it aims to provide a can be that the ultrasonic probe and an ultrasonic imaging apparatus to improve the performance of the ultrasonic wave transmission and reception in a simple structure And
本発明に係る超音波探触子は、その内部または表面に第１の電極を有する基板と、その内部または表面に第２の電極を有するダイヤフラムとを、空隙を介して配置し、
前記ダイヤフラムまたは前記第２の電極の表面または内部に、梁をそれぞれ具備した複数の超音波トランスデューサを平面状または曲面状に複数配列した超音波トランスデューサアレイを具備し、前記梁は、前記ダイヤフラムの形状に合わせて形成されている。
その他の手段については、後記する実施の形態で説明する。
An ultrasonic probe according to the present invention includes a substrate having a first electrode inside or on a surface thereof, and a diaphragm having a second electrode inside or on the surface, with a gap interposed therebetween ,
An ultrasonic transducer array in which a plurality of ultrasonic transducers each having a beam are arranged in a planar shape or a curved shape is provided on the surface or inside of the diaphragm or the second electrode, and the beam has a shape of the diaphragm. It is formed according to.
Other means will be described in an embodiment described later.
本発明によれば、簡単な構造で超音波送受信の性能を向上させることができる超音波探触子および超音波撮像装置を提供することができる。 According to the present invention, it is possible to provide an ultrasonic probe and an ultrasonic imaging apparatus that can improve the performance of the ultrasonic wave transmission and reception in a simple structure.
本実施形態においても、図１５に示すように、アレイの長軸方向の素子幅をモードによって自由に変えられるように設定することは、本発明の超音波探触子が有する広帯域特性を十分に使いこなすという観点から有益である。なお、図１５においては、複数の超音波トランスデューサをアレイ化方向と垂直な方向にのみ結線して多数の副素子を構成しておき、副素子の束ね方を変更することによってアレイの長軸方向の素子幅を変更するものであるが、図１３（ａ）あるいは図１３（ｂ）に示すように結線された複数のダイヤフラム型の超音波トランスデューサからなる素子１４を１つの副素子とし、副素子の束ね方を束ねスイッチによって変更することによって、アレイの長軸方向の素子幅をモードに応じて変更するようにしてもよい。 In this embodiment, as shown in FIG. 15, be configured to be freely changed by the mode of the long axis direction of the element width of the array is sufficiently wide band characteristic of the ultrasonic feeler element of the present invention It is useful from the viewpoint of mastering. In FIG. 15, a plurality of ultrasonic transducers are connected only in a direction perpendicular to the arraying direction to form a large number of subelements, and by changing how the subelements are bundled, the major axis direction of the array However, the element 14 composed of a plurality of diaphragm type ultrasonic transducers connected as shown in FIG. 13 (a) or 13 (b) is used as one sub-element. The element width in the long axis direction of the array may be changed according to the mode by changing the way of bundling with a bundling switch.
