摘要 |
An apparatus and method for measuring perfusion in a tissue. The method comprising the steps of recording images of the tissue under laser light, calculating a plurality of contrast images from the plurality of images of the tissue, determining a power spectrum of scattered light from the plurality of contrast images, and determining perfusion from the power spectrum. The apparatus comprises a digital video camera, a laser light source, and a processor arranged to operate the camera to produce a plurality of images with different exposure times, receive the plurality of images from the camera and process the images to determine a power spectrum and determine perfusion from the power spectrum. |
