Block regional off-resonance correction (BRORC): a fast and effective deblurring method for spiral imaging.
One primary disadvantage of spiral imaging is blurring artifact due to off-resonance effects. The conventional frequency segmented off-resonance correction method that is performed over the entire image is computationally intense due to the large number of fast Fourier transforms (FFTs) required. Here, a new fast off-resonance correction method, block regional off-resonance correction (BRORC), ...
متن کاملFast automatic linear off-resonance correction method for spiral imaging.
Field inhomogeneity and susceptibility variations, coupled with a long readout, can result in image blurring in spiral imaging. Many correction methods based on a priori off-resonance information, such as an acquired field map, have been proposed in the literature. Automatic off-resonance correction methods are alternative approaches that estimate a field map from the image data themselves. In ...
متن کاملEfficient off-resonance correction for spiral imaging.
A new spiral imaging technique incorporates the acquisition of a field map into imaging interleaves. Variable density spiral trajectories are designed to oversample the central region of k-space, and interleaves are acquired at two different echo times. A field map is extracted from this data and multifrequency reconstruction is used to form an off-resonance corrected image using the entire dat...
متن کاملFast Single Breath-hold 3D Abdominal Spiral Imaging with Water / Fat Separation and Off-resonance Correction
Introduction Large volume coverage, short total scan time and robust water/fat separation are important issues in abdominal MRI. Breath-hold approaches are often used to avoid respiratory motion artifacts, which demands for efficient sampling schemes. Spiral imaging is one of them [1], but shows high sensitivity to off-resonance [2]. Image blurring resulting from spatially varying Bo inhomogene...
متن کاملSpiral Off-Resonance Distortion Correction for Tagged MRI Using Spectral Peak Matching and HARP Refinement
INTRODUCTION: Tagging MRI is a gold standard technique [1] to estimate regional myocardial motion and strain. Harmonic phase (HARP) [2] processing is commonly used to extract motion and strain from tagged images. However, in the presence of B0 inhomogeneity, tagging lines can be significantly corrupted due to the phase accumulated during the echo time and, spatial distortion and blurring associ...
