- the site to be observed by fluorescence detection is outside the field of view Y, and enters the field of view Y with a time difference due to the rotation of the rotation unit M.
- the image information is obtained and held in advance during rotational scanning, and the fluorescence intensity distribution information of the observation target part that has been imaged is obtained later.

Abstract
Description
このようなプローブには、照射光を生体の観察対象部位に照射し病変部から放射される放射光を受光する光ファイバー等の手段が備えられている。また、観察対象部位の周囲を視覚的に確認することも求められるため、観察対象部位の画像を撮像する撮像装置を併せ持つものが提案されている。
特許文献1記載のプローブにあっては、蛍光観察方向及び撮像方向がプローブの先端方向を向いているとともに、観察対象部位から反射した光を同一光路で受光し、光分岐手段で蛍光検出及び撮像のために分光する。
特許文献1,2記載のプローブにあっては、励起光を生体の観察対象部位に照射し観察対象部位からの反射光を受光する光学系と、撮像素子とがプローブの径方向に並んでおり、蛍光観察方向及び撮影方向はプローブ先端方向を向いている。
一方、特許文献4記載のプローブにあっては、励起光は円周方向および長手方向に走査し、複数の光検出素子が円周状に配設され、上記励起光による生体観察部位が発する蛍光を受光する。
特許文献1,2記載のプローブにあっては、励起光を生体の観察対象部位に照射し観察対象部位からの反射光を受光する光学系と、撮像素子とがプローブの径方向に並んでおり、蛍光観察方向及び撮影方向はプローブ先端方向を向いている。
そのため、プローブの細径化や、プローブの側方の撮像や蛍光観察が困難である。
特許文献4記載のプローブにあっては、蛍光を受光する手段のほかに観察対象部位の表面画像を撮像する撮像手段が備えられておらず、観察対象部位の表面を視覚的に観察することができない。
前記光学系に対して、当該プローブの先端側に前記撮像装置が配置されてなるプローブである。
前記光学素子は、前記照射用光ファイバー及び前記受光用光ファイバーより当該プローブの先端側に配置され、
前記反射面を光路に介在させることにより、当該プローブの長手方向に対する垂直方向又は傾斜した方向に沿って当該プローブに入射する前記放射光を受光する請求項1に記載のプローブである。
当該プローブの長手方向に延在する軸を回動軸として、受光する前記放射光の当該プローブへの入射方向と前記撮像装置の視野方向とを、前記回動軸周りの相対角度を固定して回動するプローブである。
前記回動軸周りに前記ユニットを回動させるための回動手段を有する請求項7に記載のプローブである。
前記光学系に対して、当該プローブの先端側に前記撮像装置が配置されてなり、
当該プローブの長手方向に延在する軸を回動軸として、受光する前記放射光の当該プローブへの入射方向と前記撮像装置の視野方向とを、前記回動軸周りの相対角度を固定して回動するプローブである。
また、当該プローブの先端側に撮像装置が配置されるため、当該プローブの先端方向の撮像も容易であるという効果がある。
ユニットフレーム基端部4aは円盤状に形成され、トルクコイル3の先端に固定される。また、ユニットフレーム基端部4aは、照射用光ファイバー5及び受光用光ファイバー6を保持している。ユニットフレームは、ユニットフレーム基端部4aの周部に連続した図示しない側壁部を有して、集光レンズ7、ミラー8及び撮像カメラ9を保持している。そして、トルクコイルが回動することにより、ユニットフレーム全体が回動する。
照射用光ファイバー5及び受光用光ファイバー6の軸は、本プローブの先端方向を向いており、更に先端側に、光ファイバー側からみて、集光レンズ7、ミラー8、撮像カメラ9の順で配置されている。撮像カメラ9には撮像時に用いる図示しない照明装置も設けられている。
すなわち、励起光を生体組織の観察対象部位に照射し観察対象部位からの反射光を受光する光学系に対して、当該プローブの先端側に撮像装置が配置される。撮像カメラ9を迂回して照射用光ファイバー5及び受光用光ファイバー6を配置することは非常に困難であるから、撮像カメラ9を先端側とすることにより、照射用光ファイバー5、受光用光ファイバー6、集光レンズ7及びミラー8からなる光学系とほぼ同軸に撮像カメラ9を配置することができ、本プローブを細径化することができる。また、本プローブの先端側に撮像カメラ9が配置されるため、本プローブの先端方向の撮像も容易である。
図5A,図5B,図5C,図5Dに示すようにユニットフレーム4は円筒状に形成される。ユニットフレーム4の内部に集光レンズ7、ミラー8及び撮像カメラ9が固定され、回動ユニットMが構成される。ユニットフレーム4の周面に窓4bが設けられる。窓4bは、透明部材で構成されるか、又は開口により形成される。窓4bは励起光の出射、反射光の入射、撮像カメラ9による撮像のための照明光の出射、及び撮像カメラ9による撮像のための窓である。軸Xは、本プローブの長手方向に延在する回動軸である。
図5A,図5Bに示す構成では、先端外套2は全部が透明とされ、回動ユニットMはトルクコイル3を介して伝達される動力により先端外套2内で回動軸X周りに回動する。
図5C,図5Dに示す構成では、ユニットフレーム4は、先端外套を兼ねている。したがって、窓4bは開口でなく透明部材で構成される。図5C,図5Dに示す構成では、ユニットフレーム4は、トルク伝達可能なトルクチューブ1Aに接続され、トルクチューブ1Aの基端がアクチュエータに接続されており、回動ユニットMはトルクチューブ1Aを介して伝達される動力により回動軸X周りに回動する。トルクチューブ1Aは、例えば、トルクコイルを被覆したチューブにより構成される。
いずれの構成にあっても、特定範囲を窓4bとせず全体を透明としてもよい。
回動ユニットMに光ファイバー5,6が接続されているため、回動ユニットMの回動は、所定の回転角で規制されるようにしてある。後述する回動走査も所定の回転角(例えば、360°に達するか又は360°を超えた時点)で反転して行われる。
上述した蛍光の検出と、撮像カメラ9による撮影を行いながら、回動ユニットMを回動走査して蛍光強度分布情報と画像情報を得る。ベースユニット等に搭載されるメモリにこれを記録する。本プローブが励起光を照射した観察対象部位から反射し本プローブに入射して本プローブが受光して検出する反射光の本プローブへの入射方向は、以上の構成にあってはミラー8が決定する。この反射光の入射方向と、撮像カメラ9の視野方向との相対角が回動走査中も一定しているのでこれを特定することができ、予め定数として情報処理装置に設定しておくことで蛍光強度分布情報と画像情報とを座標の一致させた重ね合わせ画像として表示出力することができる。
蛍光強度分布情報と画像情報とを取得するための回動ユニットMの回動走査中は、バルーン10aを膨張させて回動ユニットMの回動軸Xを固定して行う。また、回動ユニットMを含むプローブ本体は、アウターチューブ10に対して軸方向に移動し、軸X方向についても連続して走査可能である。
図7A,図7Bに分解斜視図として示す構成にあっては、励起光の出射光路L1及び反射光の入射光路L2は、本プローブの回動軸Xに対して垂直であり、撮像カメラ9の視野Yと同方向を向いている。なお、図7Aではミラー8と撮像カメラ9とを離して図示しているが、図7Bに示すようにミラー8と撮像カメラ9とを回動ユニットM上に搭載されたときの間隔で描くと、蛍光検出による観察対象部位は視野Y内にある。そして、図8A,図8B,図8Cに示すように回動走査が行われる。なお、図12Aに本構成の配置模式図を示した。
図9A示す構成では、励起光の出射光路L1及び反射光の入射光路L2は撮像カメラ9の視野中心YAと180°異なっている。
図9B示す構成では、励起光の出射光路L1及び反射光の入射光路L2は撮像カメラ9の視野中心YAの軸線に対して傾斜している。
すなわち、図9A,図9Bのいずれの構成にあっても、反射光の入射方向と、撮像カメラ9による視野角θとが、回動ユニットMの回動軸X周りに相対角を有する。視野角θと相対角を有するとは、視野角θ範囲内に含まれないことを意味する。これにより、蛍光検出による観察対象部位は視野Y外にあり、回動ユニットMの回動によって視野Y内に時間差をもって入ることとなる。
本構成を用いて、回動走査中に画像情報を先に得て保持し、撮像が済んだ観察対象部位の蛍光強度分布情報を後で得て、両情報を合成して表示出力すると、リアルタイムの撮影画像に対して出力画像が遅れてしまい、検査者に対して違和感を与えるおそれがある。
したがって、本構成を用いて蛍光強度分布情報を先に得て保持し、蛍光測定が済んだ観察対象部位の画像情報を後で得て、両情報を合成することが好ましい。これにより、検査者に対して撮像時に対して時間差が小さく違和感のない画像を表示することができるという利点がある。
また、図9A,図9Bに示したように、ミラー8の撮像カメラ9に対する角度を選択することができることによって、撮像カメラ9から延出するケーブルとミラー8とが干渉しない配置を選択でき、よりミラー8と撮像カメラ9とを近接配置して、回動ユニットMを短くコンパクトにすることができるという利点がある。
図10A,図10B及び図11A,図11Bに示すように、励起光の出射光路L1及び反射光の入射光路L2を、回動軸Xに対する垂直方向よりも撮像カメラ9の視野Y側に傾斜した方向とする。これにより、視野中心YAがプローブ先端側に傾いていても、図10A,図10Bに示すように蛍光検出による観察対象部位を視野Y内に入れることができ、図11A,図11Bに示すように、蛍光検出による観察対象部位を回動ユニットMの回動によって視野Y内に時間差をもって入れることができる。図12Bには、視野中心YAが回動軸Xに対して垂直な場合において励起光の出射光路L1及び反射光の入射光路L2を視野Y側に傾斜させた構成の配置模式図を示した。ミラー8の向きを調整することで、蛍光観察用光路を垂直方向から傾け、カメラ視野に重なるようにすることができる。
回動ユニットに搭載すべき最小要素は、撮像カメラ9と、受光する反射光の当該プローブへの入射方向、すなわち、蛍光観察方向を決定する光学素子である。したがって、図13Aに示すようなミラー8と撮像カメラ9とを搭載した回動ユニットM1や、図13Bに示すような集光レンズ7とミラー8と撮像カメラ9とを搭載した回動ユニットM2、図13Cに示すような光学素子11と撮像カメラ9とを搭載した回動ユニットM3など、様々な搭載形態を選択できる。これらの回動ユニットM1,M2,M3を、例えばプローブ先端側に設置したサーボモータ12の出力端に接続することによって、回動走査を実施することができる。
すなわち、図12Bに破線で示した視野Y1のように、撮像カメラ9の視野Y1がプローブの外表面上の励起光及び受光する反射光の通過部Z1を含むように構成することも有効である。この場合、蛍光測定に悪影響を与える外表面の汚れの有無を検出することが可能となり、測定精度を維持することに役立たせることができる。
