Compressed sensing cardiac MRI exploiting spatio-temporal sparsity

چکیده
Background Compressed Sensing (CS) is a theory with potential to reconstruct sparse images from a small number of random acquisitions. Particularly in MRI, CS aims to reconstruct the image from incomplete K-space data with minimum penalty on the image quality. The image is recovered from the sub-sampled K-space data, using image sparsity in a known sparse transform domain. Cardiac MRI has a sparse structure in both temporal and spatial domains; making CS a promising method for such application.

INTRODUCTION: First-pass cardiac perfusion MRI is a promising modality for the assessment of coronary artery disease. Recently developed dynamic parallel imaging techniques, such as k-t SENSE [1] and k-t GRAPPA [2], can be used to perform up to 10-fold accelerated perfusion imaging by exploiting the difference in coil sensitivities and spatio-temporal correlations. Such techniques can be used t...

Accelerated MRI techniques reduce signal acquisition time by undersampling k-space. A fundamental problem in accelerated MRI is the recovery of quality images from undersampled k-space data. Current state-of-the-art recovery algorithms exploit the spatial and temporal structures in underlying images to improve the reconstruction quality.

In this project, we apply compressed sensing (CS) technique to achieve high-spatiotemporal functional magnetic resonance imaging (MRI), which is very challenging with conventional approaches due to physical limitations such as slew rate. We also use its ideas of exploiting sparsity for image denoising. Keywords—compressed sensing; MRI; sparsity; image denoising

متن کاملDistributed Compressed Sensing for Accelerated MRI
INTRODUCTION: Compressed sensing has recently been introduced as a powerful method to reduce the number of required samples by exploiting signal compressibility [1,2]. Application to MRI was proposed for reconstruction of images that have a sparse representation in a known transform domain (e.g. wavelets) from randomly undersampled k-space data [3]. The maximum acceleration is limited by the im...
