Cervical cancers are primarily diagnosed via colposcopy, in which the tissue is visually assessed by a clinician for abnormalities, followed by directed biopsies and histologic analysis of excised tissue. Optical biopsy technologies offer a less invasive method of imaging such that subcellular features can be resolved without removing tissue. These techniques, however, are limited in field-of-view by the distal end of the probe. We present a prototype that incorporates a rigid, machinable waveguide that is in direct contact with a fluorescently-labeled sample paired with a scanning fluorescent microscope. The system is capable of imaging large areas of tissue without the need to re-position the tissue-probe interface. A mosaicing algorithm was developed to quantify scanning shifts and stitch neighboring frames together to increase the field-of-view. Our prototype can yield a maximum axial resolution of <5 µm for individual frames and can produce mosaiced images with a field-of-view greater than 15 mm x 15 mm without sacrificing resolution. We validated the system with a 1951 USAF resolution target, fluorescent in vitro standards, and a patient study where ex vivo conization samples of squamous cervical epithelium were imaged. The results of the patient study indicate that architectural features of subcellular components could be detected and differentiated between normal tissue and precancerous lesions.
