BACKGROUND AND PURPOSE Diagnosis of AS and periaqueductal abnormalities by routine MR imaging sequences is challenging for neuroradiologists. The aim of our study was to evaluate the utility of the 3D-SPACE sequence with VFAM in patients with suspected AS. MATERIALS AND METHODS PC-MRI and 3D-SPACE images were obtained in 21 patients who had hydrocephalus on routine MR imaging scans and had cl...

OBJECTIVE To compare the accuracy of diagnosing aqueductal patency and image quality between high spatial resolution three-dimensional (3D) high-sampling-efficiency technique (sampling perfection with application optimized contrast using different flip angle evolutions [SPACE]) and T2-weighted (T2W) two-dimensional (2D) turbo spin echo (TSE) at 3-T in patients with hydrocephalus. MATERIALS AN...

This paper introduces a framework for a 3D visualization working space in which users can efficiently manipulate components associated with information/knowledge. This space with 3D graphical interfaces for knowledge/information navigation is geared on a framework based on MVC (Model-View-Controller) which has been implemented in WPF (Windows Presentation Foundation). This 3D space is integrate...

In this work, we propose a 3D space handwriting recognition system by combining 2D space handwriting models and 3D space ligature models based on that the most different parts between 2D space handwriting characters and 3D space handwriting characters are the shapes of ligatures. We design the ligature model not dependent on each character but dependent on the incoming and the outgoing vector. ...

The goal of this research is to develop a 3D topological structure to represent a 3D space partition with validation functionality and support for conversions from topological to geometrical primitives. Several 3D topological structures have been presented in the past, mainly by researchers. The technical (implementation) model developed in this paper is based on the conceptual model of the ISO...

This paper presents a new method for modelling and visualising fish aggregations in a 3D space. The concepts related to the construction of the 3D model, particularly the Delaunay triangulation generalised for a 3D space and the 3D clustering algorithm called αshapes, are discussed. Then, the proposed approach is applied to an acoustic fisheries dataset obtained from split-beam echosounder to e...

In building the 3D voxel exemplars, we voxelize a 3D CAD model into a distribution of 3D voxels. Since 3D CAD models from the web repositories, such as the Trimble 3D Warehouse [1], are usually irregular and not water-tight. We employ the volumetric depth map fusion technique, which is widely used in dense 3D reconstruction in the literature [7], to build the voxel representation of a 3D CAD mo...
