Accelerating dynamic imaging of the lung using blind compressed sensing

چکیده
Background Real time dynamic lung MRI is a promising tool to noninvasively assess lung function and mechanics. However, it potential is not realized in the clinic due to the restricted spatio-temporal resolution and volume coverage. The main focus of this work is to overcome these drawbacks using the recent blind compressed sensing (BCS) scheme [Lingala et al., IEEE TMI 2013], which enables recovery from undersampled k-t measurements.

Accelerating Magnetic Resonance Imaging through Compressed Sensing Theory in the Direction space-k
Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...

Introduction: Compressed sensing is a technique that allows accelerating data acquisition in the presence of sparse or compressible signals ([5], [6], [7]). Especially, in magnetic resonance imaging, where measurements may be time consuming, compressed sensing might give a chance to reduce the scan time. However, up to now there are no studies that examine basic imaging parameters like image no...
