Description

本発明の第１の超音波探触子は、超音波を透過する音響ウィンドウを有する筐体と、前記筐体内に配置され、かつ複数のアレイ振動子を有する振動子ユニットとを備え、前記アレイ振動子は、被検体に対して超音波を放射し、前記被検体から反射した超音波を受信する。上記課題を解決するために、前記筐体内面には、前記アレイ振動子から放射され、前記振動子ユニットの前記アレイ振動子が配列された面と前記音響ウィンドウとの間で反射された超音波を振動子ユニット外へ導く反射体が配設されたことを特徴とする。 A first ultrasonic probe according to the present invention includes a casing having an acoustic window that transmits ultrasonic waves, and a transducer unit that is disposed in the casing and includes a plurality of array transducers. The vibrator emits ultrasonic waves to the subject and receives the ultrasonic waves reflected from the subject. In order to solve the above problems, the prior Kikatami inner surface, the radiated from the array transducer, the array transducer of the transducer unit is reflected between the acoustic window and ordered surface super A reflector for guiding sound waves to the outside of the vibrator unit is provided.

本発明の超音波探触子は、上記構成を基本として種々の態様をとることができる。すなわち、本発明の第１の超音波探触子において、前記反射体は、前記アレイ振動子の配列方向における前記振動子ユニットの端部と対向する前記筐体内面に配設された構成にすることができる。
また、前記アレイ振動子が一次元状に配列され、かつ前記配列の方向と直交する方向に前記振動子ユニットを揺動させる揺動機構を備えた構成にすることができる。 The ultrasonic probe of the present invention can take various modes based on the above-described configuration. That is, in the first ultrasonic probe of the present invention, the reflector is disposed on the inner surface of the casing facing the end of the transducer unit in the array direction of the array transducer. be able to.
The array transducer may be arranged in a one-dimensional manner, and may include a swinging mechanism that swings the transducer unit in a direction orthogonal to the direction of the array.

また、前記反射体は、前記アレイ振動子から離れる向きに前記超音波を反射させる構成にすることができる。
また、前記反射体は、前記アレイ振動子の配列方向における前記アレイ振動子の中心線に頂点を有する凸状形状である反射面を有する構成にすることもできる。 The reflector may be configured to reflect the ultrasonic wave in a direction away from the array transducer.
Further, the reflector may have a reflecting surface that is a convex shape having a vertex at the center line of the array transducer in the arrangement direction of the array transducer.

また、本発明の第２の超音波探触子において、前記反射面は、前記アレイ振動子の配列方向における前記アレイ振動子の中心線に頂点を有する凸状形状である構成にすることもできる。 In the second ultrasonic probe of the present invention, the reflecting surface may also be a configuration is convex shape having a vertex at the center line of the array transducer in the array direction before SL array transducer it can.
