TISSUE IMAGES Zhao, Yunqin Biomedical Engineering Electrical Engineering optical coherence tomography medical and biological imaging We propose a simple method of linearizing spectral interference fringes of spectral domain optical coherence tomography (SDOCT) based on B-scan Doppler frequency shift (DFS), which can be obtained by offsetting the laser beam from the pivot of a scanning mirror. We show that DFS is proportional to wavenumber. A DFS curve can be then extracted from either a single mirror image or multiple tissue images. By examining the convergence of the nonlinear coefficients of the DFS curve fitted with a polynomial equation, in situ. tissue images themselves can be used to linearize the wavenumber without requiring mirror images or additional hardware. The method is verified with both ex vivo and in vivo tissue images. Using B-scan Doppler shift, we also demonstrate significantly improved imaging performance by combining complex conjugate ambiguity removal, speckle reduction, and spectral calibration with in situ. tissue images. 2019-07-08 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1562594660964602 http://rave.ohiolink.edu/etdc/view?acc_num=miami1562594660964602 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
