Compressed sensing (CS) has been introduced to accelerate data acquisition in MR Imaging. However, CS-MRI methods suffer from… Expand We describe a convergence acceleration scheme for multi-step optimization algorithms. The extrapolated solution is written as a… Expand Electron paramagnetic resonance imaging (EPRI) can yield information about the 3-dimensional (3D) spatial distribution of the… Expand In the first part of the paper we focus on two problems: (a) regularized least squares and (b) nonsmooth minimization over an… Expand We investigate an optimization-based reconstruction, with an emphasis on image-artifact reduction, from data collected in C-arm… Expand In this work, we apply non-convex, sparsity exploiting regularization techniques to image reconstruction in computed tomography… Expand PURPOSE
Iterative image reconstruction (IIR) algorithms in computed tomography (CT) are based on algorithms for solving a… Expand Baobab species are representative of the high biodiversity and endemism rates that place Madagascar in the top three of the… Expand An genuine cowpox virus was isolated in a 6-year-old girl with a circumscribed skin lesion between the thumb and forefinger. In… Expand PETRI, S. (1937).-Acta Med. Scand., Vol. XCIII, p. 450. PIRIE, A. (1943).-Brit. JI. QOphthal.. Vol. XXVII, p. 291. POCK-STEEN, P… Expand
