    Abstract: A two-by-two pixel array within an image sensor includes a first pixel, a second pixel, a third pixel, and a fourth pixel. A red filter covers the first pixel, a first blue filter covers the second pixel, a second blue filter covers the third pixel, and a green filter covers the fourth pixel. The red filter is configured to allow the first pixel to collect a red component of visible light and prevent the first pixel from collecting blue and green components of the visible light. The first and second blue filters are configured to allow the second and third pixels to each collect the blue component and prevent the second and third pixels from collecting the red and green components. The green filter is configured to allow the fourth pixel to collect the green component and prevent the fourth pixel from collecting the red and blue components.

    Abstract: Technology described herein can be embodied in a method that includes obtaining, using an endoscopic camera, a plurality of images of the surgical scene, each image in the plurality of images being obtained under illumination by electromagnetic radiation in a corresponding wavelength range. The corresponding wavelength ranges are selected in accordance with a set of chromophores present in the surgical scene, and any two of the corresponding wavelength ranges partially non-overlapping. The method also includes determining, based on the plurality of images, a concentration of each of one or more chromophores in the set at various portions of the surgical scene, and generating, by one or more processing devices, based on information about the concentration of each of the one or more chromophores, a representation of the surgical scene. The method further includes presenting the representation of the surgical scene on an output device associated with the surgical device.

    Abstract: An exemplary fluorescence imaging control system may direct, during a surgical procedure performed with a computer-assisted surgical system, an illumination source included in the computer-assisted surgical system to illuminate a scene associated with the surgical procedure with fluorescence excitation illumination configured to excite a fluorophore present at the scene and direct an imaging device included in the computer-assisted surgical system to detect, during the surgical procedure, fluorescence emitted by the fluorophore in response to excitation of the fluorophore by the fluorescence excitation illumination. The fluorescence imaging control system may determine, based on the detected fluorescence, a lifetime of the fluorescence and determine, based on the determined lifetime of the fluorescence, an identity of the fluorophore. The fluorescence imaging control system may configure, during the surgical procedure and based on the determined identity of the fluorophore, operation of the computer-assisted surgical system.

    Abstract: A system directs an imaging device to continuously capture visible light and fluorescence illumination from a surgical area. The system generates a visible light image stream based on the captured visible light and a fluorescence image stream based on the captured fluorescence illumination. The system operates in a first display mode by directing a display device to display a first video stream based on a first set of at least one of the visible light image stream and the fluorescence image stream. In response to detecting an event that occurs within the surgical area, the system switches from operating in the first display mode to operating in a second display mode by directing the display device to display a second video stream based on a second set of at least one of the visible light image stream and the fluorescence image stream, the first Instructions set being different than the second set.

    Abstract: A system includes an image sensor, an imaging pipeline, and a display device. The image sensor is configured to capture a first frame of pixel data. The imaging pipeline is coupled to the image sensor to receive the first frame of pixel data. The imaging pipeline includes an adaptive noise filter. The adaptive noise filter is configured to filter a pixel based on noise in the pixel. The imaging pipeline is configured to output a second frame of pixel data. The second frame of pixel data includes pixels filtered by the adaptive noise filter. The display device is coupled to the imaging pipeline to receive the second frame of pixel data. The display device is configured to display the second frame of pixel data.
