Optical redox imaging systems and methods

A method comprising:

• receiving an indication that a hollow probe has been inserted into the body of a person, the hollow probe having a lumen containing at least one excitation optical fiber and at least one imaging optical fiber;
• activating a first light source optically coupled to the at least one excitation optical fiber, the first light source configured to emit light that excites fluorescence of nicotinamide adenine dinucleotide (NADH) in breast tissue;
• activating a second light source optically coupled to the at least one excitation optical fiber, the second light source configured to emit light that excites fluorescence of flavin adenine dinucleotide (FAD) in breast tissue;
• conveying the NADH fluorescence and the FAD fluorescence in the at least one imaging optical fiber;
• capturing, by an image capturing device optically coupled to the at least one imaging optical fiber, image data based on the NADH fluorescence and the FAD fluorescence conveyed in at least one imaging optical fiber;
• controlling the first light source and the image capturing device to capture the image data based on the NADH fluorescence while the hollow probe is within the body of the person;
• and
• controlling the second light source and the image capturing device to capture the image data based on the FAD fluorescence while the hollow probe is within the body of the person.
