Popis: The paper is dedicated to the analysis of applicability of passive acoustic brightness (PAB) method for noninvasive detection and localization of optical heterogeneities under laser impact. To estimate the opportunities of PAB method we used computer model of multilayered medium (similar to its optical and thermophysic properties to real human tissue). It was demonstrated that PAB method allows to achieve high-quality diagnostics results in case of optical heterogeneities located in depth range less than 20 millimeters. Topics of combining PAB method with Photo-Acoustic (PAT) method were also discussed in terms of sensitizing of both approaches.
