Deconvolution-interpolation gridding (DING): accurate reconstruction for arbitrary k-space trajectories.
A simple iterative algorithm, termed deconvolution-interpolation gridding (DING), is presented to address the problem of reconstructing images from arbitrarily-sampled k-space. The new algorithm solves a sparse system of linear equations that is equivalent to a deconvolution of the k-space with a small window. The deconvolution operation results in increased reconstruction accuracy without grid...
متن کاملGridding Procedures for Non-Cartesian K-space Trajectories
1. Introduction The data collected during an MRI experiment is the spatial frequency information of the proton density of the object being imaged. The data space is referred to as k-space and is related to the image of the object through a Fourier transform relationship. When a Cartesian trajectory is used to traverse k-space, data are acquired on equally spaced grid points in k-space and a fas...
متن کاملSimultaneous Interpolation and Deconvolution Model for the 3-D Reconstruction of Cell Images
Fluorescence microscopy methods are an important imaging technique in cell biology. Due to their depth sensitivity they allow a direct 3-D imaging. However, the resulting volume data sets are undersampled in depth, and the 2-D slices are blurred and noisy. Reconstructing the full 3-D information from these data is therefore a challenging task, and of high relevance for biological applications. ...
متن کاملRe-gridding CT-data using Hermitian polynomial curve interpolation
Introduction Re-gridding of data distributed in a spatially grid to finer or coarser resolution is a fundamental task in the field of data processing. The gridding process requires a re-distribution of the original dataset to a user requested grid according to a distribution function, which can be determined on the basis of the given data by interpolation methods. Commonly used interpolation me...
متن کاملVarying kernel-extent gridding reconstruction for undersampled variable-density spirals.
Nonuniform, non-Cartesian k-space trajectories enable fast scanning with reduced motion and flow artifacts. In such cases, the data are usually convolved with a kernel and resampled onto a Cartesian grid before reconstruction. For trajectories such as undersampled variable-density spirals, the mainlobe width of the kernel for undersampled high spatial frequencies has to be larger to limit the a...
