The development of in vivo skin imaging technologies has been booming for several decades. Their advantages are indisputable, especially as they are non-invasive. Their place is already well established in onco-dermatology and it is just a question of time for them to be used with success in other fields of dermatology, including pediatric dermatology. In this paper we will discuss 3 of these skin imaging techniques used in dermatology at the CHUV, including Optical Coherence Tomography (OCT), Reflectance Confocal Microscopy (RCM) and the most recent: Line-field Confocal Optical Coherence Tomography (LC-OCT).
