      Sub-clinical assessment of atopic dermatitis severity using angiographic optical coherence tomography

      Measurement of sub-clinical atopic dermatitis (AD) is important for determining how long therapies should be continued after clinical clearance of visible AD lesions. An important biomarker of subclinical AD is epidermal hypertrophy, the structural measures of which often make optical coherence tomography (OCT) challenging due to the lack of a clearly delineated dermal-epidermal junction in AD patients. Alternatively, angiographic OCT measurements of vascular depth and morphology may represent a robust biomarker for quantifying the severity of clinical and sub clinical AD. To investigate this, angiographic data sets were acquired from 32 patients with a range of AD severities. Deeper vascular ...

    2. Optical coherence elastography for human finger-pad skin deformation studies

      Optical coherence elastography for human finger-pad skin deformation studies

      An optical coherence tomography (OCT) system with an A-scan rate of 20 kHz was developed for measuring the biomechanical properties of human finger-pad skin. Such an OCT system operates at a center wavelength of 890 nm with a spectral bandwidth of 150 nm resulting in a very good axial resolution of 2.6 μm. The measured sensitivity and sensitivity roll-off of the system were ~93 dB and ~6 dB mm -1 , respectively. Elastographic B-scan images of the human finger-pad skin were constructed by using 1000 A-scans. Deformations of the human finger-pad before and after sliding, while pressed against a transparent ...
