Multimodal Spectroscopy (MMS) for in Vivo Noninvasive Assessment of Skin

The goal of this research program is to develop a simple, noninvasive diagnostic device for assessing skin pathology without the need for a biopsy. The device being studied is a single system capable of collecting three spectroscopy measurements (Raman, diffuse reflectance and laser induced fluorescence spectroscopy) from skin lesion sites. In order to accomplish this objective, the investigators propose to: 1) develop biophysical model for Raman spectroscopy of skin cancers, 2) conduct a clinical pilot study to collect MMS data from a minimum of 250 patients to determine the diagnostic accuracy (sensitivity and specificity) of MMS for diagnosing skin malignancy.
