A Functional Anatomic Defect of the Cystic Fibrosis Airway

Rationale: The mechanisms underlying cystic fibrosis (CF) lung disease pathogenesis are unknown. Objective: To establish mechanisms linking anion transport with the functional microanatomy, we evaluated normal and CF piglet trachea, as well as adult swine trachea in the presence of …

An Automatic Algorithm for Segmentation of the Boundaries of Corneal Layers in Optical Coherence Tomography Images using Gaussian Mixture Model

Diagnosis of corneal diseases is possible by measuring and evaluation of corneal thickness in different layers. Thus, the need for precise segmentation of corneal layer boundaries is inevitable. Obviously, manual segmentation is time-consuming and imprecise. In this paper, the Gaussian …

To Be or not TB?

Relative to other specialties, ophthalmologists deal infrequently with uncertainty. Of course, every patient requires advice, which in turns requires a weighing of risks and benefits, and some pondering of potential unknowns. But unlike internists, ophthalmologists often see the pathology directly. …

Multi-Surface and Multi-Field Co-Segmentation of 3-D Retinal Optical Coherence Tomography

When segmenting intraretinal layers from multiple optical coherence tomography (OCT) images forming a mosaic or a set of repeated scans, it is attractive to exploit the additional information from the overlapping areas rather than discarding it as redundant, especially in …
