Diffusion-weighted MRI of the body has the potential to provide important new insights into physiological and microstructural properties. The intra-voxel incoherent motion (IVIM) model relates the observed DW-MRI signal decay to parameters that reflect perfusivity (D*) and its volume fraction (f), and diffusivity (D). However, the commonly used voxel-wise fitting of the IVIM model leads to para...

Numerical estimation of the size of the kidney is useful in evaluating conditions of the kidney, especially, when serial MR imaging is performed to evaluate the kidney function. This paper presents a new method for automatic segmentation of the kidney in three-dimensional (3D) MR images, by extracting texture features and statistical matching of geometrical shape of the kidney. A set of Wavelet...

Water vapor is a dominant greenhouse gas. It significantly impacts the atmosphere by trapping heat and infrared radiation. The effect essential for life on Earth but can also be harmful. Although amount of water in not much during cycle, it most active element rapid changes both spatial temporal domains. GNSS tomography’s ability to model high-resolution 3D distribution promising means measurin...

A parametric voxel-based jewelry modeler is developed for designing carved bangles of sophisticated craftsmanship. Carved jewelry is the form of jewelry having small internal repeated cavities as engraved with a thin sharp tool on the surface of sheet metal. The parameters’ values are defined by the user and modeling of the jewelry design is carried out by the modeler based on the specified val...

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...

Zusammenfassung. Computergestützten dreidimensionalen Modellen des menschlichen Körpers fehlt es bisher meist an Realismus und Detaillierung. In diesem Beitrag wird ein Modell der inneren Organe entwickelt, das auf über 770 Cryotomschnitten und den dazu kongruenten CT-Schnittbildern aus dem Visible Human-Projekt der National Library of Medicine basiert und eine bisher unerreichte photorealistis...
