Abstract
Description
この出願は、(Ian E. McDowell et al.が2016年9月9日に出願した「SIMULTANEOUS WHITE LIGHT AND HYPERSPECTRAL LIGHT IMAGING SYSTEMS」という名称の)米国特許出願第62/385,700号の優先権及び利益を主張する。
ディスプレイモード選択252からのユーザ入力に応答して、一定ハイパースペクトル照明を伴う増強視認モードを示す増強ディスプレイ選択コマンドが、ユーザインタフェース261の視認モード確認プロセス302に提供される。一定ハイパースペクトル照明コマンドを備える増強視認モードに応答して、確認プロセス302は、この態様において、可視画像処理パイプライン310内の白色光で組織を照らすプロセス303にアクティブ白色光照明制御信号を提供し、ハイパースペクトル画像処理パイプライン320内のハイパースペクトル光で組織を照らすプロセス321にアクティブハイパースペクトル一定照明制御信号提供する。
ハイパースペクトル画像処理パイプライン230の先の例では、ハイパースペクトル照明が時間及びスペクトルにおいて一定であること、並びに、シーンを横断してカメラをスキャンしてハイパースペクトルフレームを取り込み、取り込まれるシーンの部分が時間に関して移動させられたとしてもハイパースペクトルフレームを組み合わせて複合フレームを形成することができることが想定された。しかしながら、別の例において、ハイパースペクトル照明のスペクトルは、時間と共に順次的に変化し、ハイパースペクトルフレームは、ハイパースペクトル照明の各時間順次波帯に亘って或いは代替的にハイパースペクトル照明の各時間順次波長に亘って取り込まれる。本明細書で使用するとき、ハイパースペクトル光の波帯(waveband)は、ハイパースペクトル光のスペクトルである。波帯が単一の波長のみを含むならば、波帯(典型的には、波長の範囲)及び波長は同じものである。やはり、取り込まれるシーンの態様は、時間と共に移動することができるので、同じシーンが各フレーム内に取り込まれることがある一方で、取り込まれるシーン内の要素の場所はフレーム毎に異なり得る。
Detection Using Waveband Selective imaging」を開示する)米国特許出願第62/092,651号明細書を参照のこと。
図8Aは、時定ハイパースペクトル照明源及び白色光照明源を備えるカメラ220L及び220Rとしての使用に適した画像キャプチャユニット920の1つの態様の例示である。内視鏡101内の1以上の照明チャネルからの光は、この例において、組織103を照らす。図8Aには示されていないが、内視鏡101の視野内の1以上の手術器具も、照明チャネル又は複数の照明チャネルからの光を介して照らされてよい。内視鏡内の照明チャネル又は複数の照明チャネルの使用は、例示的であるに過ぎず、本明細書に提示する様々な例に限定されることを意図しない。照明は、内視鏡内の照明源によって或いは内視鏡の内部又は外部にある他の装置によって提供されてよい。
図10Aは、可視フレーム及びハイパースペクトルフレームを同時に取り込む新規な画像キャプチャユニットを含む更に別の内視鏡1150の例示である。内視鏡1150は、内視鏡1011の一例である。
上記の例では、平面視又は立体視の内視鏡が、1つの態様において、コンピュータ支援手術システムのアームに取り付けられ、他の手術器具が、コンピュータ支援手術システムの別のアームに取り付けられた。図1を参照のこと。別の態様では、単一の入口ポートが使用される。図11Aは、全てが有線(電気的又は光学的)又は無線接続1296によって相互接続された、内視鏡撮像システム1292、外科医コンソール1294(マスタ)、及び患者側支持システム1210(スレーブ)を含む、手術システム1200の態様を例示する概略側面図である。1以上の電子データプロセッサが、システム機能性を提供するためにこれらの主要コンポーネント内に様々に配置されてよい。複数の例が、本明細書に参照として援用する米国特許出願第11/762,165号に開示されている。
