Abstract
Some embodiments of the present inventive concept provide a multispectral imaging system including a first light source, the first light source having a first wavelength configured to produce a non-coherent illumination to image a sample; a second coherent light source, different from the first light source, having a second wavelength, different from the first wavelength, configured to image the sample simultaneously with the first light source; a camera configured to simultaneously receive information related to the first and second light sources from the sample, wherein light at the first wavelength is configured to image a surface of the sample into the camera and light at the second wavelength is configured to penetrate the sample and provide information related to the penetrated sample to the camera; and a processor configured to combine the received information related to the first and second light sources and generate a synthesized image of the anatomical structure and the physiology of blood flow and perfusion of the sample in terms of blood flow rate distribution.
