Partially parallel imaging with localized sensitivities (PILS).
In this study a novel partially parallel acquisition method is presented, which can be used to accelerate image acquisition using an RF coil array for spatial encoding. In this technique, Parallel Imaging with Localized Sensitivities (PILS), it is assumed that the individual coils in the array have localized sensitivity patterns, in that their sensitivity is restricted to a finite region of spa...
متن کاملRegularization in Parallel Imaging Reconstruction
INTRODUCTION The recent advance of the parallel MRI technology, which utilizes multiple RF receiver array coils [1], has also demonstrated the capability to enhance the spatiotemporal resolution of MRI [2, 3]. In parallel MRI, there exist two major sources in image reconstruction: the first is the reduced data samples in accelerated scans compared to the unaccelerated scans. The second source o...
متن کاملParallel Magnetic Resonance Imaging Reconstruction
The acquisition speed of magnetic resonance imaging (MRI) is an important issue. Increasing the acquisition speed shortens the total patient examination time, it reduces motion artifacts and increases the frame rate of dynamic MRI. Parallel MRI is a way to use multiple receiver coils with distinct spatial sensitivities to increase the MRI acquisition speed. The acquisition is speeded up by unde...
متن کاملParallel Imaging Reconstruction I: Cartesian
Introduction Parallel Imaging is an effective way of accelerating MRI acquisitions. It works by replacing some of the Fourier encoding with spatial sensitivity encoding from multiple localized receiver coils. Fewer k-space locations are visited during the acquisition and to compensate for the missing data, information about the spatial sensitivities of the receiver coils is incorporated into th...
