    Abstract: A system includes a controller communicatively coupled to an illuminator and to a camera configured to capture a scene including tissue. The controller may change the output optical power of the illuminator from a first output optical power to a second output optical power so that a subsequently captured frame is captured by the camera from reflected light, the reflected light being light from the illuminator having the second output optical power prior to being reflected. The controller may determine that an endoscope contacted the tissue if the change of the output optical power of the illuminator results in a change of a reflected luminance that is less than a predetermined threshold, the change of the reflected luminance being a change from a first reflected luminance for the first output optical power to a second reflected luminance for the second output optical power.

    Abstract: Technology described herein can be embodied in a method of displaying a visual representation of a portion of a surgical scene. The method includes receiving data representing information captured using a first sensor of a camera associated with a surgical device, the information being indicative of a first quantity representing an amount of fluorescence emitted from the portion of the surgical scene. The method also includes obtaining information indicative of a second quantity representing an amount of excitation signal causing the fluorescence to be emitted from the portion of the surgical scene, and generating a normalized fluorescence signal as a function of the first quantity and the second quantity. The method further includes generating the visual representation of the portion of the surgical scene based on the normalized fluorescence signal, and presenting the visual representation on a display device associated with the surgical device.

    Abstract: The technology described herein can be embodied in a method that includes receiving data representing information captured using a first sensor and a second sensor of a multi-sensor camera. The sensors are configured to capture a surgical scene illuminated by a light source configured to emit wavelengths in the visible spectrum corresponding to sensing capabilities of the first and second sensors, respectively. The method also includes receiving data representing information captured using a third sensor of the multi-sensor camera, the third sensor configured to capture the surgical scene as illuminated by a near-infrared light source, and generating a first visual representation of the surgical scene based on the data representing the information captured using the first and second sensors. The first visual representation is combined with the information captured using the third sensor to generate a second visual representation, and the second visual representation is presented on a display device.

    Abstract: The technology described herein can be embodied in a method that includes obtaining a representation of a first image of a surgical scene using electromagnetic radiation of a first wavelength range outside the visible range of wavelengths, wherein an amount of electromagnetic radiation of the first wavelength range received from a first tissue type is lower than that received for a second tissue type. The method also includes obtaining a representation of a second image using electromagnetic radiation of a second wavelength range outside the visible range of wavelengths, wherein an amount of electromagnetic radiation of the second wavelength range received from the second tissue type is substantially different from that received for the first tissue type. The visual representation of the surgical scene is rendered on the one or more displays using the representation of the first image and the representation of the second image.

    Abstract: Mixed mode imaging is implemented using a single-chip image capture sensor with a color filter array. The single-chip image capture sensor captures a frame including a first set of pixel data and a second set of pixel data. The first set of pixel data includes a first combined scene, and the second set of pixel data includes a second combined scene. The first combined scene is a first weighted combination of a fluorescence scene component and a visible scene component due to the leakage of a color filter array. The second combined scene includes a second weighted combination of the fluorescence scene component and the visible scene component. Two display scene components are extracted from the captured pixel data in the frame and presented on a display unit.
