چکیده

A variety of image artifacts are routinely observed on MRI images. We concentrate on the Gibbs Ringing that manifests itself as bright or dark rings seen at the borders of abrupt intensity change on the images. Gegenbauer High Resolution Reconstruction method has been previously shown to eliminate the undesirable ringing at the jump discontinuities in MRI. Prior work concentrated on applying this reconstruction method on frequency data obtained from reconstructed images and not on raw K-space data obtained from the MRI scanning machine. Our project work concentrates on using the raw k-space data for reconstruction and aims at comparing the reconstructed images obtained to those reconstructed from other commonly used reconstruction methods.

SPECTRAL SAMPLING AND DISCONTINUITY DETECTIONMETHODS WITH APPLICATION TO MAGNETIC RESONANCE IMAGING by

Typical implementations of Fourier methods demand acquisition and evaluation of input and output data on a Cartesian grid. This presents a problem in applications such as magnetic resonance imaging (MRI), where non-Cartesian input measurements are available. The reconstruction of support-limited functions from such non-Cartesian spectral data constitutes the subject matter of this thesis. A sur...

An investigation into the effect of magnetic resonance imaging (MRI) echo time spacing and number of echoes on the sensitivity and dose resolution of PAGATUG polymer-gel dosimeter

Background: There are various methods to read out responses of a polymer-gel dosimeter, among which the Magnetic Resonance Imaging (MRI) technique is the most common one. Optimizing imaging protocols can have significant effect on the sensitivity and the dose resolution of polymer gel dosimeters. This study has investigated the effects of the number of echoes (NOE) and the echo time spacing (ES...

Improving tissue segmentation of human brain MRI through preprocessing by the Gegenbauer reconstruction method.

The Gegenbauer image reconstruction method, previously shown to improve the quality of magnetic resonance images, is utilized in this study as a segmentation preprocessing step. It is demonstrated that, for all simulated and real magnetic resonance images used in this study, the Gegenbauer reconstruction method improves the accuracy of segmentation. Although it is more desirable to use the k-sp...

Methods to Improve Fiber Reconstruction at DTI-Based Tractography in the Area of Brain Tumor: Case Illustration and Literature Review

Background and Aim: DTI-based tractography could help us to visualize the spatial relation of fiber tracts to brain lesions. Several factors may interfere with the procedure of diffusion-based tractography, especially in brain tumors. The aim of the current study is to discuss several solutions to improve the procedure of fiber reconstruction adjacent or inside brain lesions. Illustrative cases...
