    Abstract: A system and method for controlling an emitter assembly for visualizing a surgical site is disclosed. The emitter assembly is configured to emit a pulse pattern of electromagnetic radiation at the surgical site. The electromagnetic radiation pattern can include infrared radiation, visible light, or combinations thereof in either structured or non-structured formats. Further, a receiver assembly is configured to receive the electromagnetic radiation reflected from the surgical site. The control circuit can be configured to control the sequence or pattern in which the electromagnetic radiation is pulsed according to a preset sequence or according to feedback from the surgical site.

    Abstract: Systems, methods, and devices for fluorescence imaging with a minimal area image sensor are disclosed. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation, wherein the pixel array comprises active pixels and optical black pixels. The system includes a black clamp providing offset control for data generated by the pixel array and a controller comprising a processor in electrical communication with the image sensor and the emitter. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of: electromagnetic radiation having a wavelength from about 770 nm to about 790 nm; or electromagnetic radiation having a wavelength from about 795 nm to about 815 nm.

    Abstract: Systems, methods, and devices for hyperspectral imaging in a light deficient environment are disclosed. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The system includes a controller comprising a processor in electrical communication with the image sensor and the emitter, wherein the controller synchronizes timing of the pulses of electromagnetic radiation during a blanking period of the image sensor. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of electromagnetic radiation having a wavelength from about 513 nm to about 545 nm, electromagnetic radiation having a wavelength from about 565 nm to about 585 nm, or electromagnetic radiation having a wavelength from about 900 nm to about 1000 nm.
