Automatic Retinal Layer Segmentation in OCT Images Based on Deep Learning
Chong_Wei Kao;Chieh-En Lee;Jin-Shing Tseng;Chu-Ming Cheng;Chung-Hao Tien
Precise retinal layer segmentation in optical coherence tomography (OCT) helps early clinical diagnosis of some diseases. In this work, we established a segmentation algorithm for the retinal layer boundaries based on deep learning. Our method successfully segments three retinal layers with acceptable errors compared to traditional methods.

Label-free Histopathology of Alzheimer’s Disease Human Brain by Harmonic Generation Microscopy
Ying-Ting Huang;Sandeep Chakraborty;Sung-Tsang Hsieh;Ming-Jang Chiu;Hwan-Ching Tai;Chi-Kuang Sun
Here, we demonstrated a label-free, sub-micron multi-harmonic generation microscopy to elucidate the histopathological hallmarks of Alzheimer’s disease human brain ex vivo. Our harmonic generation microscopy has shown the capability to differentiate simultaneously structures of brain viz. axons, soma along with AD pathological hallmarks: Aβ-plaques and neurofibrillary tangles.

Human Intra-epidermal Nerve Fiber Imaging using Stain-free Trauma-free in vivo Harmonic Generation Microscopy
Hsiao-Chieh Tseng;Pei-Jhe Wu;Chi-Kuang Sun;Yi-Hua Liao
Diabetic neuropathy is diagnosed by skin biopsy to quantify intra-epidermal nerve fiber. Our recent study indicated the capability of third-harmonic-generation microscopy (THGM) to image intra-epidermal free-nerve endings. In this study, we successfully apply the stain-free trauma-free THGM to in vivo evaluate epidermal innervation by quantifying the number of nerve fibers.

Optically sectioned mechanical-scan-free endomicroscopy with hybrid illumination
Chi-Hao Luo;Haw Hsiao;Yuan Luo;Kuang-yuh Huang
Optical sectioning in our system is achieved by HiLo imaging technique. High speed hybrid illumination for background elimination is generated by a digital micro-mirror device (DMD),with electrically tunable lens (ETL) as a mechanical-scan-free device. Our system offers multiple advantages, which may enable large scale dynamic imaging of biological tissues.

Stain-free Imaging of Human Intra‐epidermal Free Nerve Endings by using Third Harmonic Generation Microscopy
Pei-Jhe Wu;Hsiao-Chieh Tseng;Sung-Tsang Hsieh;Yi-Hua Liao;Chi-Kuang Sun
We demonstrate the first observation of the intra‐epidermal free-nerve-endings (IFNEs) with histopathology details by third-harmonic-generation on ex vivo human skin. With the high image contrast, noninvasiveness, high resolution, high penetration of harmonic generation microscopy, we aim to label-free slide-free in vivo image IFNEs for the peripheral neuropathy diagnosis.
