A clinical probe for combined Raman spectroscopy/optical coherence tomography (RS-OCT) of the skin cancers
Skin cancer is the most commonly occurring cancer, with incidence rates rising annually. Realizing favorable outcomes requires early diagnosis, for which the current standard is biopsy followed by histopathology. This process can be invasive, subjective, time consuming, and costly. Optical techniques, including Optical Coherence Tomography (OCT) and Raman Spectroscopy (RS), have been developed to perform non-invasive characterization of skin lesions, however neither is without limitation. Here, we demonstrate a clinical instrument for morphological and biochemical characterization of skin cancers with combined RS-OCT. The portable instrument utilizes independent RS and OCT system backbones, and is integrated in a common clinical probe ...
