A novel graph-based optimal segmentation method which can simultaneously segment multiple star-shaped surfaces is presented in this paper. Minimum and maximum surface distance constraints can be enforced between different surfaces. In addition, the segmented surfaces are ensured to be smooth by incorporating surface smoothness constraints which limit the variation between adjacent surface voxels....
Spectral-domain optical coherence tomography (SD-OCT) is used clinically for the diagnosis and management of glaucoma, with the internal limiting membrane (ILM) being one important structure of interest as it reflects the upper bounding surface of the optic cup. In cases of severe glaucoma, the boundary of the optic cup can become very steep and difficult to segment. Because of this difficulty, current...
Neonatal jaundice could occur in most neonates and phototherapy is one of the most important therapeutic methods. The optical system of neonatal jaundice phototherapy apparatus based on LED was reported in this paper. Modeling and simulation of fly-eye lens which could be used to generate uniform illumination has been conducted and parameters have been optimized. The simulation results show that in...
