Abstract
Description
本願は、その出願があらゆる目的のために参照することによってその全体として本明細書に組み込まれる2019年4月8日に出願された米国仮特許出願第62/830,934号、および2019年12月23日に出願された米国仮特許出願第62/952,892号の優先権を主張する。
医療撮像技術(例えば、内視鏡等の検鏡アセンブリ)が、医療または外科手術手技中の対象または患者の内部解剖学的または生理学的特徴の画像またはビデオデータを捕捉するために使用され得る。捕捉される画像またはビデオデータは、医療従事者(例えば、外科医、医療オペレータ、技師等)に患者または対象内の内部構造またはプロセスの可視化を提供するために、処理および操作され得る。
本開示は、従来の医療撮像システムの少なくとも前述の欠点に対処する。一側面では、本開示は、1つ以上の医療撮像技術(例えば、検鏡アセンブリ)と適合性のある光学アダプタを提供する。ある場合、光学アダプタは、染料の使用の必要性を伴わずに、標的部位の追加または複数の特徴の可視化を可能にし得る。
本明細書に言及される全ての刊行物、特許、および特許出願は、各個々の刊行物、特許、または特許出願が具体的かつ個々に参照することによって組み込まれることが示される場合と同程度に、参照することによって本明細書に組み込まれる。参照することによって組み込まれる刊行物および特許または特許出願が、本明細書に含まれる開示と矛盾する範囲で、本明細書は、任意のそのような矛盾する資料に優先および/または先行することを意図している。
本発明の種々の実施形態が、本明細書に示され、説明されているが、そのような実施形態が、例としてのみ提供されることが、当業者に明白であろう。多数の変形例、変更、および代用が、本発明から逸脱することなく、当業者に想起され得る。本明細書に説明される本発明の実施形態の種々の代替が、採用され得ることを理解されたい。
ある側面では、本開示は、本開示の方法、例えば、医療撮像のための本主題の方法のうちのいずれかを実装するようにプログラムまたは別様に構成されたコンピュータシステムを提供する。図11は、医療撮像のための方法を実装するようにプログラムまたは別様に構成されたコンピュータシステム1701を示す。コンピュータシステム1701は、例えば、(i)白色光をコヒーレントレーザ光と組み合わせ、組み合わせられた光ビームを発生させるように照明源に指示し、(ii)組み合わせられた光ビームを検鏡アセンブリの検鏡に提供するように照明源に指示し、(iii)組み合わせられた光ビームによる照明時に対象の標的部位によって反射または放出される光信号の少なくとも一部を受け取るように光学アダプタの画像センサに指示するように構成され得る。コンピュータシステム1701は、ユーザの電子デバイスまたは電子デバイスに対して遠隔で位置するコンピュータシステムであり得る。電子デバイスは、モバイル電子デバイスであり得る。
