Abstract
An endoscopic imaging system for use in a light deficient environment includes an imaging device having a tube, one or more image sensors, and a lens assembly including at least one optical elements that corresponds to the one or more image sensors. The endoscopic system includes a display for a user to visualize a scene and an image signal processing controller. The endoscopic system includes a light engine having an illumination source generating one or more pulses of electromagnetic radiation and a lumen transmitting one or more pulses of electromagnetic radiation to a distal tip of an endoscope.
Claims19
A system comprising:
- an endoscope for use in a light deficient environment comprising an image sensor;
- a light engine, wherein the light engine comprises a plurality of illumination sources that each generate one or more pulses of electromagnetic radiation;
- a controller in electrical communication with the light engine and the image sensor;
- wherein the image sensor receives reflected electromagnetic radiation from the one or more pulses of electromagnetic radiation to generate one or more exposure frames;
- and
- wherein at least a portion of the one or more pulses of electromagnetic radiation is emitted onto a surface of a body tissue to generate three-dimensional data and to track a location of an object in the light deficient environment;
- wherein the three-dimensional data is processed to determine one or more of a distance from the endoscope or a tool to the object, surface area information about the object, a size of one or more surgical tools, a size of one or more structures, a size of one or more anatomical structures, or other positional data and metrics about the object within the light deficient environment.
