In this paper, a new multiresolution reconstruction approach for fan-beam tomography is established. The theoretical development assumes radial wavelets. An approximate reconstruction formula based on a near-radial quincunx multiresolution scheme is proposed. This multiresolution algorithm allows to compute both the quincunx approximation and detail coefficients of an image from its fan-beam projections. Simulations on mathematical phantoms show that wavelet decomposition is acceptable for…

Nonseparable wavelet-based cone-beam reconstruction in 3-D rotational angiography
TLDR
A fast low-resolution reconstruction of the 3-D arterial vessels with the progressive addition of details in a region of interest is demonstrated and the improvement of image quality by denoising techniques and also the reduction of computing time using the space localization of wavelets.
Robust multiresolution techniques for image reconstruction
TLDR
It is shown that it is possible to express many physical problems in a wavelet framework, thereby allowing the derivation of efficient algorithms that take advantage of wavelet properties, such as multiresolution structure, sparsity, and space-frequency decompositions.

Multigrid Reconstruction in Tomographic Imaging
TLDR
The efficacy of the multigrid reconstruction principle is demonstrated using simulated data for quantitative assessment and experimental measurements from a clinically relevant use case scenario, and the expected artefacts from coarse discretization outside the region of interest become noticeable only for large differences in discretizations between subregions.

Local tomography in fan-beam geometry using wavelets
TLDR
An algorithm is developed for wavelet based multiresolution reconstruction of a function directly from its fan beam projections that can reduce the X-ray dosage down to 22% of full exposure in the cases where only a local region of the cross section of a body is to be reconstructed.

It is shown how the separable two-dimensional wavelet representation leads naturally to an efficient multiresolution tomographic reconstruction algorithm, which can be significantly reduced, compared to a standard reconstruction.
Wavelet-based multiresolution local tomography

The proposed method uses the properties of wavelets to localize the Radon transform and can be used to reconstruct a local region of the cross section of a body, using almost completely local data that significantly reduces the amount of exposure and computations in X-ray tomography.
