Patent number: 11770503Abstract: 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.Type: GrantFiled: April 28, 2021Date of Patent: September 26, 2023Assignee: Stryker European Operations LimitedInventors: Paul R. Westwick, David Potkins, John Fengler

Patent number: 11025867Abstract: An endoscopic video system and method using a camera with a single color image sensor, for example a CCD color image sensor, for fluorescence and color imaging and for simultaneously displaying the images acquired in these imaging modes at video rates in real time is disclosed. The tissue under investigation is illuminated continuously with fluorescence excitation light and is further illuminated periodically using visible light outside of the fluorescence excitation wavelength range. The illumination sources may be conventional lamps using filters and shutters, or may include light-emitting diodes mounted at the distal tip of the endoscope.Type: GrantFiled: November 3, 2016Date of Patent: June 1, 2021Assignee: Stryker European Operations LimitedInventors: Paul R.

Patent number: 10779734Abstract: An imaging system for acquisition of NIR and full-color images includes a light source providing visible light and NIR light to an area under observation, such as living tissue, a camera having one or more image sensors configured to separately detect blue reflectance light, green reflectance light, and combined red reflectance light/detected NIR light returned from the area under observation. A controller in signal communication with the light source and the camera is configured to control the light source to continuously illuminate area under observation with temporally continuous blue/green illumination light and with red illumination light and NIR excitation light. At least one of the red illumination light and NIR excitation light are switched on and off periodically in synchronism with the acquisition of red and NIR light images in the camera.Type: GrantFiled: May 2, 2017Date of Patent: September 22, 2020Assignee: Stryker European Operations LimitedInventors: John Fengler, Paul R.

Patent number: 7420151Abstract: A system for performing short wavelength imaging with a broadband illumination source includes an image processor that receives signals from a color image sensor. The image processor reduces the contribution of red illumination light to an image by computing blue, green, and blue-green (cyan) color components of display pixels from the signals received from the image sensor. The blue, green, and cyan color component values are coupled to inputs of a color monitor for display to produce a false color image of the tissue.Type: GrantFiled: October 10, 2006Date of Patent: September 2, 2008Assignee: Novadaq Technologies Inc.Inventors: John J.
