Brief Summary

Optical coherence tomography (OCT) is an established medical imaging technique that uses light to capture biological images from within optical scattering media (e.g., biological tissue). A high-resolution OCT has the characteristics of non-invasive, label-free, real-time, cellular resolution with high tissue penetration depth that are highly valuable for clinical use. AMO has developed an in-vivo OCT scanning system prototype based on the clinical needs and potential applications. This study is designed as an early feasibility study aiming for validation of AMO's in-vivo OCT scanning system in dermatology through collaboration with Mackay Memorial Hospital. The OCT can provide cellular-resolution (\<1μm in lateral and axial directions) images which can be utilized to identify organelles. A high-resolution OCT has the characteristics of non-invasive, label-free, real-time, cellular resolution with high tissue penetration depth that are highly valuable for clinical use. The proposed scenario in this study is to collecting OCT images of skins with suspicious lesion including tumor, inflammatory diseases or pigment alteration as well as normal skin by using AMO's in vivo OCT imaging system. By using traditional pathological biopsy images or dermoscopic images as gold standard references, investigators will try to identify different characteristics in OCT images of skin with suspicious lesion including tumor, inflammatory diseases, or pigment alteration as well as normal skins.

Outcome Measures

Primary Outcomes (2)

• Number of subjects with clear tissue characteristics of skin diseases and/or normal skin in tomograms

  Number of subjects with clear tissue characteristics of tomograms will be compared to that with unclear tissue characteristics to identify the effect of the OCT on scanning skin at study completion.

  2 years

• Number of subjects with the distinction between skin lesion and normal skin in tomograms

  Number of subjects with the distinction between skin lesion and normal skin in tomograms will be compared to that with no distinction to verify the specific diseases that can be distinguished from others by the OCT at study completion.

  2 years

Secondary Outcomes (2)

• Number of subjects with clear tissue stratification of skin diseases and/or normal skin in tomograms

  2 years

• Number of subjects with the similarity of tissue characteristics, tissue stratification, and tissue thickness between tomograms and H&E stain

  2 years
