Description
幾つかの実施形態によれば、少なくとも1つの画像化器は画素アレイを具備する。各々の画素は所定の画素サイズbを有する。b/fは、0.01−0.0015ラジアンから0.01+0.0015ラジアンの範囲内にある。
幾つかの実施形態によれば、第1光学レンズは対物レンズであり、先端から距離D’に位置する。
本発明は、添付の図面に関連して得られる次の詳細な記述からより完全に理解および評価されるであろう。
に述べられる。しかし当業者には、本発明が、これらの特定の詳細なしに、実行可能であることは理解されるであろう。他の例では、本発明を不明瞭にしないように、周知の方法、手順、および構成要素は、詳細には記述されていない。
は照明源34、レンズホルダ32,32’、および画像化器36,36’が位置する。本発明の幾つかの実施形態によれば、画像化装置40は、本装置の2つの端部から、たとえば消化管のような身体内腔の画像を同時に得ることができる。たとえば本発明の一実施形態によれば、画像化装置40は、前方端部および後方端部を有した円筒状のカプセルであることが可能である。カプセルは消化管全体を通過できる。前方端部と後方端部は、画像化装置40の長手方向および長手方向軸を規定可能である。レンズホルダ32,32’と画像化器36,36’は、長手方向軸に沿って位置可能である。それぞれの画像化器36,36’は、長手方向軸に対して垂直であることが可能である。円筒状のカプセルにおける本システムは、カプセルの前方および後方の消化管を画像化できる。画像は、同時にまたは連続的に送信され、別々にまたは単一の組合わせた画像として表示可能である。
画像化装置40の外部には、外部受信器90と恐らく外部送信器が存在可能である。外部受信器90と外部送信器は、同一のハウジングまたはユニットに収容または包含可能であるか、または一または複数の別個のユニットに収容可能である。外部受信器90と外部送信機は、典型的にはアンテナもしくはアンテナアレイを備えるか、またはこれらを付随する。外部受信器90と外部送信機は、たとえば患者によって携帯または着用されるか、または一体化可能な携帯ユニットに収容可能である。
器を介した画像化装置40への制御コマンドを処理する外部コントローラを具備可能である。本発明の他の実施形態では、制御コマンド以外の信号は、たとえば外部コントローラと外部プロセッサ92によって処理され、外部送信器を介して送信可能である。更に他の実施形態では、外部コントローラと外部プロセッサ92は、互いに電気的通信可能状態にあることが可能な別個のユニット同士であることが可能である。
273からの光は、レンズホルダ232,232’を具備可能な光学システムを使用して反射、集光、および偏向可能であり、そして画像化器236,236’によって受信可能である。よって位置271,273の画像をキャプチャ可能である。レンズホルダ232,232’は、長手方向軸に沿って位置可能である。
いるときに使用可能である。一方、より小さな開口は、たとえば小腸のようなより小さな身体内腔内を画像化するために使用可能である。
