Accelerated 3D phase-contrast imaging using adaptive compressed sensing with no free parameters
Introduction Compressed Sensing (CS) theory [1] allows one to use the sparsity of images in a transform domain (e.g. wavelets) effectively to enable image reconstruction with sub-Nyquist sampled data. While CS methodologies present several potential benefits for medical imaging applications (e.g. reduced scan times, higher resolution imaging, etc.), their successful implementation on clinical s...
متن کاملAccelerated MR diffusion tensor imaging using distributed compressed sensing.
PURPOSE Diffusion tensor imaging (DTI) is known to suffer from long acquisition time in the orders of several minutes or even hours. Therefore, a feasible way to accelerate DTI data acquisition is highly desirable. In this article, the feasibility and efficacy of distributed compressed sensing to fast DTI is investigated by exploiting the joint sparsity prior in diffusion-weighted images. MET...
متن کاملImaging through turbulence using compressive coherence sensing.
Previous studies have shown that the isoplanatic distortion due to turbulence and the image of a remote object may be jointly estimated from the 4D mutual intensity across an aperture. This Letter shows that decompressive inference on a 2D slice of the 4D mutual intensity, as measured by a rotational shear interferometer, is sufficient for estimation of sparse objects imaged through turbulence....
متن کاملAccelerated late gadolinium enhancement cardiac MR imaging with isotropic spatial resolution using compressed sensing: initial experience.
PURPOSE To evaluate the use of low-dimensional-structure self-learning and thresholding (LOST) compressed sensing acquisition and reconstruction in the assessment of left atrial (LA) and left ventricular (LV) scar by using late gadolinium enhancement (LGE) magnetic resonance (MR) imaging with isotropic spatial resolution. MATERIALS AND METHODS The study was approved by the local institutional...
متن کاملAccelerated Cest Mri Using Compressive Sensing and Multishot Spiral Acquisitions
Fig.2 CEST acceleration: (a) shows the recovered CEST images at the z shift corresponding to maximum CEST contrast. (b) indicates the average of the z spectra at two regions of interest, one within the yolk (top) and the other within the white regions (bottom). Note that the degradation in the performance is graceful with acceleration. 6711 ACCELERATED CEST MRI USING COMPRESSIVE SENSING AND MUL...
