    Abstract: The invention relates to imaging methods and systems. The systems may comprise a white light source configured to generate light in a first wavelength range, an excitation source configured to generate light at one or more wavelengths for exciting a fluorescent substance, a first detector configured to acquire reflectance image data that represents white light reflected from a subject, and a second detector configured to acquire fluorescence image data that represents fluorescence emissions from the subject. At least one of the one or more wavelengths generated by the excitation light source is within the first wavelength range of the white light source. The fluorescent substance may be, for example, a fluorescent dye that is injected into a patient before or during a surgery. The system may also include an image processing engine and a display. The image processing engine may receive the reflectance image data and the fluorescence image data and generate a merged image in which the fluorescence image data is superimposed on the reflectance image data. The display may be used by a surgeon, for example, to more effectively visualize the surgical site during surgery.
