Abstract
Description
図1は、本発明の実施の形態に係る内視鏡システム1を模式的に示す図である。内視鏡システム1は、超音波の性質を利用して、超音波を被検体、例えば被検体内の体壁に当て、その反射を映像化するシステムである。この内視鏡システム1は、図1に示すように、内視鏡2と、画像処理装置3と、光源装置4とを備える。内視鏡2は、一部を被検体内に挿入可能とし、被検体の体腔で超音波を送信するとともに被検体にて反射された反射エコー(超音波エコー)を受信してエコー信号を出力する機能を有する超音波内視鏡である。内視鏡2は、エコー信号を受信して該エコー信号に応じた超音波画像を生成する画像処理装置3、および照明用の光源を有する光源装置4とケーブルを介して接続可能である。
上述した実施の形態では、切欠き面62aを有する段部63を一つ設けるものとして説明したが、この限りでない。例えば、二以上の複数の段部を設けて、接合レンズが、光軸のまわりに回転したときの組み付けの自由度を向上させるようにしてもよい。
