Abstract
There has been a growing interest in the development of a low cost depth-resolved non-invasive dermis imaging tool for both clinical and fundamental investigations of skin diseases. Multiple reference optical coherence tomography (MR-OCT) is a recently developed miniature time-domain low coherence interferometeric imaging platform, which promises to fit into robust, cost-effective designs that are virtually solid state, typical of handheld devices. In this paper we demonstrate the feasibility of MR-OCT for dermis imaging applications by incorporating it in a dermascope, which provides simultaneous imaging of dermis and an interactive tool for beam steering and registration of the OCT imaging beam at the dermis area. This allows the user to interactively investigate the depth resolved information of any target position of interest on the dermis by pointing the mouse cursor within the dermis image or selecting the area on a touch screen. Image acquisition is controlled with software that displays both the dermis and MR-OCT axial-scan, and allows detailed information of the depth scan signal to screen for skin disease. We believe this approach will have a significant impact on medical care.
