Abstract

The last few decades have seen the emergence of a huge number of optical imaging techniques. Among them, full-field optical coherence tomography (FF-OCT) has become valuable for many biomedical applications. Indeed, FF-OCT is a noninvasive and label-free imaging technique that produces high-resolution 3D microscopic images of scattering biological samples. However, FF-OCT images alone lack of specificity for accurate diagnosis. That is why it is necessary to add new contrast modalities to FF-OCT technique such as elastography. Indeed, coupling FF-OCT with shear wave elastography allows quantitative estimation of the stiffness at a resolution of a few micrometers. We present here our first results on coupling single-shot off-axis FF-OCT (SO-FF-OCT) method with transient shear wave elastography method.
