Optical coherence tomography (OCT) is a noninvasive optical imaging technique for in vivo and in situ imaging of microstructure in biological tissues. Improvements in identification, imaging, and visualization of biological microstructures are necessary before OCT clinical use. Using the proposed algorithm, OCT images of the prostate and cervicovaginal epithelium were segmented to differentiate the cavernous nerves from the prostate gland and to detect minute changes in the epithelial layer, respectively. To detect these nerves and epithelial layer changes, three image features were employed: Gabor filter, Daubechies wavelet, and Laws filter. The Gabor feature was applied with different standard deviations in ...
BACKGROUND AND OBJECTIVE: To compare rates of abnormal peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell layer scans acquired with Cirrus HD-OCT (Carl Zeiss Meditec, Inc., Dublin, CA) and RTVue-100 (Optovue Inc., Fremont, CA) in healthy myopic eyes. PATIENTS AND METHODS: Forty-one non-glaucomatous myopic eyes (41 individuals) were scanned with Cirrus to measure RNFL and ganglion cell-inner plexiform layer (GCIPL) and with RTVue to measure peripapillary RNFL and ganglion cell complex (GCC) thicknesses. Rates of abnormal scans were calculated and compared between devices. Inter-device agreement in falsely classifying scans as abnormal was also assessed RESULTS: The rate of ...
University of North Carolina was chartered in 1789, and was the first public university in the United States and the only one to graduate students in the eighteenth century. Today, UNC is a multi-campus university composed of all 16 of North Carolina's public institutions that grant baccalaureate degrees, as well as the NC School of Science and Mathematics, the nation's first public residential high school for gifted students.
