Fluorophores associated with early development of cancer (FAD, NADH, collagen) and abnormalities in microvessel structure have been shown to correlate with oral cancer progression. Co-registered imaging approaches using optical coherence tomography (OCT) and fluorescence imaging techniques have demonstrated promise in assessing these biomarkers, but current endoscopic approaches are limited in specificity. We propose that a micromotor-based OCT angiography and fluorescence-lifetime imaging microscopy (FLIM) may provide a suitable biopsy guidance tool for oral cancer screening. We present initial work towards implementing these modalities with a micromotor catheter system, validated with phantoms. Performance is compared to our existing OCT-autofluorescence system.
