Programmable multispectral illumination system for surgery and visualization of light-sensitive tissues

摘要

An observation system for viewing light-sensitive tissue includes an illumination system configured to illuminate the light-sensitive tissue, an imaging system configured to image at least a portion of the light-sensitive tissue upon being illuminated by the illumination system, and an image display system in communication with the imaging system to display an image of the portion of the light-sensitive tissue. The illumination system is configured to illuminate the light-sensitive tissue with a reduced amount of light within a preselected wavelength range compared to multispectral illumination light, and the image of the portion of the light-sensitive tissue is compensated for the reduced amount of light within the preselected frequency range to approximate an image of the light-sensitive tissue under the multispectral illumination.

1. An observation system for viewing light-sensitive tissue, comprising:
an illumination system; an imaging system arranged to be in an optical path of light from said light-sensitive tissue upon being illuminated by said illumination system, said imaging system comprising an optical detector and a data processing system; and an image display system in communication with said imaging system to display an image of said portion of said light-sensitive tissue, wherein said illumination system comprises a light source and a light source controller constructed and arranged to control at least one of a spectral composition and intensity of light that illuminates said light-sensitive tissue, wherein said imaging system is configured to image at least a portion of said light-sensitive tissue upon being illuminated by said illumination system; wherein said illumination system is configured to illuminate said light-sensitive tissue with a reduced amount of light within a preselected wavelength range compared to substantially white light illumination, wherein said light source controller causes said light source to illuminate said light-sensitive tissue with substantially white light for a first period of time and with light that is non-toxic to said light-sensitive tissue for a second period of time thus providing said reduced amount of light within said preselected wavelength range, wherein said light source controller communicates with said imaging system such that said optical detector acquires imaging data during said first period of time and during said second period of time, wherein said data processing system uses said imaging data acquired during said first period of time to compensate said imaging data acquired over said second period of time such that said image displayed by said image display system appears more like an uninterrupted white-light-illuminated image, and wherein said image of said portion of said light-sensitive tissue is a full color image.
