Accelerated cine DENSE MRI using compressed sensing and parallel imaging
Background Cine DENSE (Displacement Encoding with Stimulated Echoes) provides accurate and high-resolution displacement and strain imaging of the heart; however, image acquisition times are relatively long and, due to properties inherent to stimulated echoes, signal-to-noise ratio (SNR) is relatively low. Accelerated cine DENSE could substantially shorten scan times and/or provide improved spat...
متن کاملParallel Magnetic Resonance Imaging Using Compressed Sensing
Although magnetic resonance imaging (MRI) is routinely used in clinical practice, long acquisition times limit its practical utility in many applications. To increase the data acquisition speed of MRI, parallel MRI (pMRI) techniques have recently been proposed. These techniques utilize multi-channel receiver arrays and are based on simultaneous acquisition of data from multiple receiver coils. ...
متن کاملImpact of Coil Sensitivity Estimation on MRI reconstruction methods Combining Compressed Sensing and Parallel MRI
INTRODUCTION: Parallel MRI has been used widely to accelerate image acquisition [1,2]. Recently, application of compressed sensing (CS) to MRI has been proposed and showed great promise [3]. It is reported that combining parallel MRI and CS can enable further acceleration in MRI acquisition [4,5]. SparseSENSE directly applies CS to SENSE by using a random under-sampling pattern and a regulariza...
متن کاملData Acquisition Considerations for Compressed Sensing in MRI
INTRODUCTION Compressed sensing (CS) theory [1-3] provides a methodology with which compressible signals, such as MR images, can often be recovered using a small of measurements. This result has been applied successfully to significantly accelerate various MRI experiments by acquiring only a small set of quasi-randomly selected k-space measurements [4,5]. However, the specific choice of data ac...
متن کاملDeep artifact learning for compressed sensing and parallel MRI
Purpose: Compressed sensing MRI (CS-MRI) from single and parallel coils is one of the powerful ways to reduce the scan time of MR imaging with performance guarantee. However, the computational costs are usually expensive. This paper aims to propose a computationally fast and accurate deep learning algorithm for the reconstruction of MR images from highly down-sampled k-space data. Theory: Based...
