This paper describes a framework for establishing a reference airway tree segmentation, which was used to quantitatively evaluate fifteen different airway tree extraction algorithms in a standardized manner. Because of the sheer difficulty involved in manually constructing a complete reference standard from scratch, we propose to construct the reference(More)
Clinical exome sequencing (CES) has become an increasingly popular diagnostic tool in patients with heterogeneous genetic disorders, especially in those with neurocognitive phenotypes. Utility of CES in consanguineous populations has not yet been determined on a large scale. A clinical cohort of 149 probands from Qatar with suspected Mendelian, mainly(More)
A segmentation framework for the identification of human airway trees in high resolution computed tomography (CT) images is presented. This framework consists of a fully automated segmentation algorithm, supplemented by software editing tools that allow the user to correct the airway segmentation result if needed. The algorithm and tools presented in this(More)

Automated fundus image analysis plays an important role in the computer aided diagnosis of ophthalmologic disorders. A lot of eye disorders, as well as cardio-vascular disorders, are known to be related with retinal vasculature changes. Many studies has been done to explore these relationships. However, most of the studies are based on limited data obtained(More)
ii ACKNOWLEDGMENTS This work would not have been possible without the contributions of many. The first person I would like to acknowledge is David Stoltz. I thank him for the opportunity to further my education and to participate in engrossing, exciting, meaningful, and dynamic research. I would also like to specially thank the Stoltz Lab members including
The main function of the respiratory system is gas exchange. Since many disease or injury conditions can cause biomechanical or material property changes that can alter lung function, there is a great interest in measuring regional lung function and mechanics. In this thesis, we present a technique that uses multiple respiratory-gated CT images of the lung(More)
