Uniform angular resolution integral imaging display with boundary folding mirrors.
نویسندگان
چکیده
Uniform angular resolution integral imaging display is proposed. Conventionally, inefficient bias of the perspectives around boundaries is disregarded and it is impossible to display the field of view over full spatial resolution. However, the proposed display has four boundary folding mirrors and these mirrors fold the view volumes correctly to form uniform angular resolution within them. The distribution of perspectives and field of view in the proposed system are analyzed and the removal of this boundary effect is confirmed experimentally.

Determination of Fiber Direction in High Angular Resolution Diffusion Images using Spherical Harmonics Functions and Wiener Filter
Diffusion tensor imaging (DTI) MRI is a noninvasive imaging method of the cerebral tissues whose fibers directions are not evaluated correctly in the regions of the crossing fibers. For the same reason the high angular resolution diffusion images (HARDI) are used for estimation of the fiber direction in each voxel. One of the main methods to specify the direction of fibers is usage of the spher...
متن کاملCAS WAVELET METHOD FOR THE NUMERICAL SOLUTION OF BOUNDARY INTEGRAL EQUATIONS WITH LOGARITHMIC SINGULAR KERNELS
In this paper, we present a computational method for solving boundary integral equations with loga-rithmic singular kernels which occur as reformulations of a boundary value problem for the Laplacian equation. Themethod is based on the use of the Galerkin method with CAS wavelets constructed on the unit interval as basis.This approach utilizes the non-uniform Gauss-Legendre quadrature rule for ...
متن کاملPanoramic 3D Reconstruction Using Rotating Camera with Planar Mirrors
In this paper, we propose a novel approach for obtaining 3D information of panoramic (360 degrees) environments. We design an image acquisition rig composed with a camera and two planar mirrors. The regular image captured by the camera is separated into uncontinuous three regions by the mirrors arranged in front of the camera. By rotating the rig about a vertical axis with a constant velocity, ...
متن کاملCalculation of Positron Distribution in the Presence of a Uniform Magnetic Field for the Improvement of Positron Emission Tomography (PET) Imaging Using GEANT4 Toolkit
Introduction Range and diffusion of positron-emitting radiopharmaceuticals are important parameters for image resolution in positron emission tomography (PET). In this study, GEANT4 toolkit was applied to study positron diffusion in soft tissues with and without a magnetic field for six commonly used isotopes in PET imaging including 11C, 13N, 15O, 18F, 68Ga, and 82Rb. Materials and Methods GEA...
متن کاملEffect of windowing and zero-filled reconstruction of MRI data on spatial resolution and acquisition strategy.
Standard, MR spin-warp sampling strategies acquire data on a rectangular k-space grid. That method samples data from the "corners" of k-space, i.e., data that lie in a region of k-space outside of an ellipse just inscribed in the rectangular boundary. Illustrative calculations demonstrate that the data in the corners of k-space contribute to the useful resolution only if an interpolation method...
