Realtime cardiac function using compressed sensing: initial clinical evaluation
Methods Study population and acquisitions 14 patients with different cardiac pathologies were randomly selected. All patients underwent our clinical routine imaging protocol and additionally real-time (RT) imaging in three short axis slices (apical, medial, basal). RT imaging was performed with a radial Tiny Golden Angle (Ψ7≍23.628°) [2] balanced acquisitions (a=60°) at 1.5T (Philips Achieva 1....
متن کاملAccelerating global cardiac function assessment in mice using compressed sensing
Introduction: Cine magnetic resonance imaging (cine-MRI) to assess global cardiac function in surgically or genetically modified mice is typically performed using single dedicated volume or surface coils, precluding the use of parallel imaging techniques to speed up the imaging process. Compressed sensing has been shown to accelerate the data acquisition process in MRI by sparse coding the sign...
متن کاملFrames for compressed sensing using coherence
We give some new results on sparse signal recovery in the presence of noise, for weighted spaces. Traditionally, were used dictionaries that have the norm equal to 1, but, for random dictionaries this condition is rarely satised. Moreover, we give better estimations then the ones given recently by Cai, Wang and Xu.
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...
