Subsurface Cutaneous Imaging Techniques

Abstract

Surface skin imaging has long been the only non-invasive way for skin imaging reflecting only the image provided by the stratum corneum, however in the past few decades, thanks to the technological development, sub-surface skin imaging have been made possible providing non-invasive in depth cutaneous images by means of dermoscopy, optical coherence tomography, cutaneous ultra-sonography and Laser confocal microscopy. This review aims at providing insight into each of these modalities.
