In this paper, we present a novel vasculature segmentation algorithm that incorporates the knowledge of both vascular anatomy and imaging modality. In particular, emphasis is put on the segmentation of main cerebral vessels such as the Circle of Wills. The algorithm segments cerebral vasculature in two major steps. One is vasculature candidate calculation using local intensity distribution, where...
An axial flux permanent magnet (AFPM) machine with dual rotors and single air-cored stator is studied in this paper. The machine is applied for vertical-shaft small power off-grid wind generating system. A 2-dimensional (2D) finite element analysis (FEA) method is proposed to approximately solve to the 3-dimensional (3D) magnetic field inside the AFPM machine. And a 2D analytical method is also presented...
This paper introduces an interactive and intelligent approach for accurate brain segmentation. A high resolution 3-Tesla magnetic resonance (MR) dataset was tested by state of the art automated algorithms as well as segmented by making use of the proposed interactive tools. The results show that the automated algorithms gave an incomplete or anatomically incorrect brain surface. About 4% false positive...
