Abstract
A method of displaying a colorized luma image includes illuminating tissue under observation with illumination light and excitation light. A color image from reflectance of the illumination light and a fluorescence image produced by illuminating the tissue under observation with the excitation light are simultaneously detected at an image sensor to produce image data comprising both color image data and fluorescence image data. A luma image from the detected color image data is computed and the luma image is colorized based on the detected fluorescence image data. The colorized luma image is then displayed.
Claims29
A method of displaying a colorized luma image comprising:
- illuminating tissue under observation with illumination light and excitation light;
- simultaneously detecting at an image sensor a color image from reflectance of the illumination light and a fluorescence image produced by illuminating the tissue under observation with the excitation light to simultaneously produce image data comprising a combination of color image data and fluorescence image data, wherein the color image data and the fluorescence image data at least partially overlap;
- computing a luma image from the detected color image data;
- colorizing the luma image based on the detected fluorescence image data;
- and
- displaying the colorized luma image.
A system for visualizing tissue under observation comprising:
- an illumination device having a illumination light source and an excitation light source that emits excitation light having a predetermined wavelength for exciting a fluorescent dye;
- one or more image sensors for simultaneously detecting a color image and a fluorescence image to simultaneously produce image data comprising a combination of color image data and fluorescence image data, wherein the color image data and the fluorescence image data at least partially overlap, and wherein at least one of the one or more image sensors that is used for detecting the color image is also used to detect the fluorescence image;
- and
- a processing system configured to compute a luma image from the detected color image, colorize the luma image based on the detected fluorescence image, and output a colorized luma image to a display, wherein the system is configured to simultaneously produce image data comprising both color image data from reflectance of the illumination light and fluorescence image data.
A method of displaying a colorized luma image of tissue of a subject, the method comprising:
- administering a fluorescent dye to the subject;
- illuminating the tissue with illumination light and excitation light;
- detecting a color image from reflectance of the illumination light and simultaneously detecting a fluorescence image produced by illuminating the tissue with the excitation light to simultaneously produce image data comprising a combination of color image data and fluorescence image data, wherein the color image data and fluorescence image data at least partially overlap, and wherein at least one image sensor that is used for detecting the color image is also used to detect the fluorescence image;
- computing a luma image from the detected color image data;
- colorizing the luma image based on the detected fluorescence image data;
- and
- displaying the colorized luma image.
