Iterative reconstruction in diffraction tomography using nonuniform fast Fourier transform
نویسندگان
چکیده
We show an iterative reconstruction framework for diffraction ultrasound tomography. The use of broadband illumination allows significantly reduce the number of projections compared to straight ray tomography. The proposed algorithm makes use of fast forward nonuniform Fourier transform (NUFFT) for iterative Fourier inversion. Incorporation of total variation regularization allows reduce noise and Gibbs phenomena whilst preserving the edges.

Iterative Tomographic Image Reconstruction Using Nonuniform Fast Fourier Transforms
Fourier-based reprojection methods have the potential to reduce the computation time in iterative tomographic image reconstruction. Interpolation errors are a limitation of Fourier-based reprojection methods. We apply a min-max interpolation method for the nonuniform fast Fourier transform (NUFFT) to minimize the interpolation errors. Numerical results show that the min-max NUFFT approach provi...
متن کاملNUFFT-Based Iterative Image Reconstruction via Alternating Direction Total Variation Minimization for Sparse-View CT
Sparse-view imaging is a promising scanning method which can reduce the radiation dose in X-ray computed tomography (CT). Reconstruction algorithm for sparse-view imaging system is of significant importance. The adoption of the spatial iterative algorithm for CT image reconstruction has a low operation efficiency and high computation requirement. A novel Fourier-based iterative reconstruction t...
متن کاملSparse-View Ultrasound Diffraction Tomography Using Compressed Sensing with Nonuniform FFT
Accurate reconstruction of the object from sparse-view sampling data is an appealing issue for ultrasound diffraction tomography (UDT). In this paper, we present a reconstruction method based on compressed sensing framework for sparse-view UDT. Due to the piecewise uniform characteristics of anatomy structures, the total variation is introduced into the cost function to find a more faithful spa...
متن کاملTHE FAST SINC TRANSFORM AND IMAGE RECONSTRUCTION FROM NONUNIFORM SAMPLES IN k-SPACE
A number of problems in image reconstruction and image processing can be addressed, in principle, using the sinc kernel. Since the sinc kernel decays slowly, however, it is generally avoided in favor of some more local but less precise choice. In this paper, we describe the fast sinc transform, an algorithm which computes the convolution of arbitrarily spaced data with the sinc kernel in O.N lo...
متن کاملFast, iterative, field-corrected image reconstruction for MRI
Magnetic field inhomogeneities cause distortions in the reconstructed images for non-cartesian k-space MRI (using spirals, for example). Several noniterative methods are currently used to compensate for the off-resonance during the reconstruction, but these methods rely on the assumption of a smoothly varying field map. Recently, iterative methods have been proposed that do not rely on this ass...
