Optical Elastography and Tissue Biomechanics II
We present a dual wavelength endoscope which uses Endoscopic Laser Speckle Contrast Analysis (ELASCA) with the aim to image tissue blood flow and perfusion during surgical procedures. In this study we measure speckle decorelation times, which are associated with flow, by imaging speckle patterns at a wide range of detector exposure times. In order to understand the effects of image collection efficiency and sample scattering properties, control experiments with different optical systems weredoi:10.1117/12.2078225 fatcat:kx4yz7lkwfampkhb22hqboe5be
