Title
(JA) バレット食道検診用のテザー付きカプセル内視鏡
Abstract
(JA)

カプセル(20)がテザー(22)に結合され、このテザーが操作されて、カプセルとこのカプセルに内蔵されたスキャナ(26)とを患者の体内の内腔内部の所望の箇所に位置決めする。バレット食道(BE)を示す特徴な暗いピンク色を検出するために、カプセル中のスキャナが胃の上方の食道領域を走査することを可能にするように、カプセルが飲み込まれてテザーで位置決めされると、スキャナによって作成された画像を使用してBEおよび早期(無症状の)食道癌を検出することができる。スキャナは、内表面の一部を照明するために所望のパターンで動作する。次いで、内表面からの光が、カプセル中の検出器によって受け取られるか、または導波路を介して外部に搬送されて外部検出器に達する。電気信号が、スキャナを動作させるアクチュエータ(28)を励起するために印加される。カプセルは、他の内腔における診断および/または治療目的にも使用することができる。
