Abstract
Methods and systems for imaging tissue of a subject are disclosed, and involve illuminating the tissue with a coherent light having a coherent wavelength, acquiring image data of the tissue using a color image sensor, and processing the image data using laser speckle contrast analysis while correcting for differences in sensitivity of color pixels at the coherent wavelength to generate a perfusion image of the tissue. The perfusion image is then displayed to the user. Also disclosed are methods and systems for correcting for ambient light and for acquiring white light images along with laser speckle images.
