Abstract
Nowadays, methods of non-invasive analysis are in great demand. Tissue clearing is one of the main methods of non-invasive diagnostics of diseases. In this work, tissue clearing is combined with laser speckle imaging, which is a powerful, accurate and, at the same time, relatively inexpensive and easy-in-use instrument for non-invasive research. In the experiment, glycerin was used as a clearing agent and the dura mater was used as an object. The object is cleared according to a cyclical algorithm: until the object is significantly cleared in glycerin, then it is placed in a NaCl solution for a couple of minutes until its scattering properties are restored, then the object is again placed in an optical clearing agent. Such a multi-stage scheme leads to a higher degree of clearing of the dura mater, as shown in the obtaine results of the experiment.
