Sparse MRI: The Application of Compressed Sensing for Rapid MR Imaging
- MAGNETIC RESONANCE IN MEDICINE 58:1182–1195
, 2007
"... The sparsity which is implicit in MR images is exploited to significantly undersample k-space. Some MR images such as angiograms are already sparse in the pixel representation; other, more complicated images have a sparse representation in some transform domain–for example, in terms of spatial finit ..."

Application of compressed sensing for rapid MR imaging
- in SPARS
, 2005
"... In a typical magnetic resonance imaging (MRI) experiment, samples are collected in the so-called k-space or frequency domain of the image. The number of samples needed for reconstruction at a given resolution and field of view is ..."

Rapid MR imaging with Compressed Sensing and randomly under-sampled 3DFT trajectories
- in Proc. 14th

Rapid MR-ARFI Method for Focal Spot Localization During Focused Ultrasound Therapy
"... MR-guided focused ultrasound (FUS) is a noninvasive therapy for treating various pathologies. MR-based acoustic radiation force imaging (MR-ARFI) measures tissue displacement in the focal spot due to acoustic radiation force. MR-ARFI also pro-vides feedback for adaptive focusing algorithms that coul ..."

. The effect of the phase aberrations on the ultrasound focusing was studied using displacement maps obtained with echo-planar imaging and two-dimensional spin-warp MR-ARFI. The results show that displacement in the focal spot can be rap-idly imaged using echo-planar imaging–based MR-ARFI with high signal
Raxml-iii: a fast program for maximum likelihood-based inference of large phylogenetic trees
- Bioinformatics
, 2005
"... Motivation: The computation of large phylogenetic trees with statistical models such as maximum likelihood or bayesian inference is computationally extremely intensive. It has repeatedly been demonstrated that these models are able to recover the true tree or a tree which is topologically closer to ..."

Rapid 3D Segmentation of the Carotid Bifurcation from Serial MR Images
"... The current trend in computational hemodynamics is to employ realistic models derived from ex vivo or in vivo imaging. Such studies typically produce a series of images from which the lumen boundaries must first be individually extracted (i.e. 2D segmentation), and then seriallyreconstructed to prod ..."

to produce the three-dimensional lumen surface geometry. In this paper, we present a rapid 3D segmentation technique that combines these two steps, based on the idea of an expanding virtual balloon. This 3D technique is demonstrated in application to finite element meshing and CFD modeling of flow
