Optical fiber waveguide in an endoscopic system for hyperspectral, fluorescence, and laser mapping imaging

A system comprising:

• an endoscope;
• an emitter that emits electromagnetic radiation, wherein the emitter comprises a plurality of electromagnetic sources;
• an image sensor;
• a waveguide that receives the electromagnetic radiation pulsed by the emitter and carries the electromagnetic radiation to a distal end of the endoscope, wherein the waveguide comprises a plurality of optical fibers;
• and
• a controller in communication with the emitter and the image sensor;
• wherein the plurality of electromagnetic sources of the emitter comprises:
• a visible source tuned to pulse broadband electromagnetic radiation only within a visible waveband of the electromagnetic spectrum;
• a first multispectral source tuned to pulse narrowband visible electromagnetic radiation only within a visible waveband that is 20 nm wide or less without use of a filter;
• a second multispectral source tuned to pulse narrowband infrared electromagnetic radiation only within an infrared waveband that is 20 nm wide or less without use of a filter;
• and
• a fluorescence source tuned to pulse a fluorescence excitation wavelength of electromagnetic radiation;
• wherein the controller instructs the plurality of electromagnetic sources of the emitter to independently actuate each of the plurality of electromagnetic sources according to a pulse cycle;
• wherein the pulse cycle comprises actuating each of the plurality of electromagnetic sources in a repeating pattern, and wherein one of the plurality of electromagnetic sources within the repeating pattern is actuated per frame on a successive frame basis;
• wherein electromagnetic radiation emitted by each of the first multispectral source and the second multispectral source elicits a spectral response from a tissue;
• wherein each wavelength within the visible waveband of the first multispectral source and the infrared waveband of the second multispectral source elicits a different spectral response;
• wherein the image sensor receives the elicited spectral response and reads out spectral data;
• wherein the plurality of optical fibers of the waveguide is arranged such that each of the plurality of optical fibers receives substantially an equivalent portion of the electromagnetic radiation emitted by the emitter;
• and
• wherein the emitter provides energy to the plurality of electromagnetic sources such that the substantially equivalent portion of the electromagnetic radiation received by each of the plurality of optical fibers remains below a burnout threshold for the plurality of optical fibers.
