Skin imaging is a research area that involves the use of various imaging techniques to capture detailed images of the structure and properties of human skin. This field encompasses a wide range of technologies, including optical coherence tomography (OCT), confocal microscopy, multispectral imaging, and dermoscopy. Skin imaging can be used for various purposes such as diagnosing skin conditions, monitoring treatment outcomes, and studying the effects of aging and environmental factors on the skin. Researchers in this area aim to improve the accuracy, resolution, and speed of skin imaging techniques to enhance their clinical utility and expand their applications in dermatology and other fields.
