Journal ArticleDOI
Accelerated diffusion spectrum imaging in the human brain using compressed sensing.
Marion I. Menzel,Ek Tsoon Tan,Kedar Khare,Jonathan I. Sperl,Kevin F. King,Xiaodong Tao,Christopher J. Hardy,Luca Marinelli +7 more
TL;DR: A novel method to accelerate diffusion spectrum imaging using compressed sensing can be applied to either reduce acquisition time of diffusion spectrum Imaging acquisition without losing critical information or to improve the resolution in diffusion space without increasing scan time.
Journal ArticleDOI
Single shot high resolution digital holography
TL;DR: This approach which is unlike the physical hologram replay process is shown to provide high quality image recovery even when the dc and the cross terms in the hologram overlap in the Fourier domain.
Journal ArticleDOI
Two-dimensional phase unwrapping using the transport of intensity equation.
TL;DR: The TIE is solved by employing the regularized Fourier-transform-based approach and the resultant phase profile is automatically in the unwrapped form, as it has been obtained as a solution of a partial differential equation rather than as an argument of a complex-valued function.
Journal ArticleDOI
Sampling theory approach to prolate spheroidal wavefunctions
Kedar Khare,Nicholas George +1 more
TL;DR: In this article, the Whittaker-Shannon sampling theorem is used to show that the eigenvalue problem for the sinc-kernel is equivalent to a discrete eigen value problem.
Journal ArticleDOI
Accelerated MR imaging using compressive sensing with no free parameters
TL;DR: In this article, the authors describe and evaluate a robust method for compressive sensing MRI reconstruction using an iterative soft thresholding framework that is data-driven, so that no tuning of free parameters is required.
