Abstract
Multispectral imaging systems are provided including a first light source having a first wavelength configured to image a sample; a second light source, different from the first light source, having a second wavelength, different from the first wavelength, configured to image the sample; and at least a third light source, different from the first and second light sources, having a third wavelength, different from the first and second wavelengths, configured to image the sample. A camera is configured to receive information related to the first, second and at least third light sources from the sample. A processor is configured to combine the information related to the first, second and at least third light sources provided by the camera to image an anatomical structure of the sample, image physiology of blood flow and perfusion of the sample and/or synthesize the anatomical structure and the physiology of blood flow and perfusion of the sample in terms of a blood flow rate distribution. The imaging system is directed and focused on a field of view (FOV) in a region of interest of the sample using an endoscope.
