Simulation of tagged MR images with linear tetrahedral solid elements.
نویسندگان
چکیده
Computer simulation of tagged magnetic resonance (MR) images is presented using signals derived from connected solid triangular or tetrahedral elements. Simulation provides precisely-known deformations for validating tag quantification algorithms. MR imaging signal is derived by Fourier-transforming over a standard element, then mapping to actual elements via transformations. Linear intensity variations over the element are interpolated from vertex intensities determined by tag calculations.

Construction of Hexahedral Block Topology and its Decomposition to Generate Initial Tetrahedral Grids for Aerodynamic Applications
Making an initial tetrahedral grid for complex geometry can be a tedious and time consuming task. This paper describes a novel procedure for generation of starting tetrahedral cells using hexahedral block topology. Hexahedral blocks are arranged around an aerodynamic body to form a flow domain. Each of the hexahedral blocks is then decomposed into six tetrahedral elements to obtain an initial t...
متن کاملHex-Dominant Mesh Generation with Directionality Control via Packing Rectangular Solid Cells
A new computational method that creates a hex-dominant mesh of an arbitrary 3D geometric domain is presented. The proposed method generates a high-quality hexdominant mesh by: (1) controlling the directionality of the output hex-dominant mesh; and (2) avoiding ill-shaped elements induced by nodes located too closely to each other. The proposed method takes a 3D geometric domain as input and cre...
متن کاملFinite Element Modeling of the Human Foot and Footwear
A finite element (FE) model of the human foot and ankle was developed from 3D reconstruction of 2 mm coronal MR images from the right foot of a normal male subject using the segmentation software, Mimics. Solid models of 28 foot bones and encapsulated soft tissue structures models established in Solidworks software were imported into ABAQUS for creating the tetrahedral FE meshes. The plantar fa...
متن کاملBandpass Optical Flow for Tagged MR Imaging
MR tagging has shown great promise for detailed noninvasive cardiac motion imaging. We consider here the use of low-frequency tags coupled with gradientbased optical flow estimation to compute cardiac motion. A multiple constraint optical flow method for tagged MRI is formulated by exploiting the Fourier content of the tagged images. The method is validated on simulated tagged data. Keywords— o...
متن کاملEfficient Symmetric Boundary Condition for Galerkin Finite Volume Solution of 3D Temperature Field on Tetrahedral Meshes
In some of the engineering problems, it is necessary to analyze the three-dimensional temperature profiles. In order to solve a typical problem numerically, the three-dimensional temperature diffusion equation is chosen as the mathematical model. The finite volume formulation is derived using Galerkin approach for the mesh of tetrahedral elements, which facilitates solving temperature problems ...
