Tomographic Reconstruction from Noisy Data
نویسندگان
چکیده
A generalized maximum entropy based approach to noisy inverse problems such as the Abel problem, tomography, or deconvolution is discussed and reviewed. Unlike the more traditional regularization approach, in the method discussed here, each unknown parameter (signal and noise) is redefined as a proper probability distribution within a certain pre-specified support. Then, the joint entropies of both, the noise and signal probabilities, are maximized subject to the observed data. We use this method for tomographic reconstruction of the soft x-ray emissivity of hot fusion plasma.

Conventional Voxel in Tomographic Reconstruction Based upon Plane-Integral Projections – Use It or Lose It?
Introduction: While the necessity of replacing voxels with blobs in conventional tomographic reconstruction based upon line-integrals is clear, it is not however well-investigated in plane- integral-based reconstruction. The problem is more challenging in convergent-plane projection reconstruction. In this work, we are aiming at utilizing blobs as alternative to voxels. <stron...
متن کاملWavelet Transfonn-Based Multi-Resolution Techniques For Tomographic Reconstruction And Detection
In this thesis we have presented multi-resolution approaches to the problem of reconstruction and detection of objects from tomographic measurements. Such problems are commonly encountered in many applications including medical imaging, non-destructive testing and evaluation, astronomy, geophysics, and oceanography. We have focused our efforts mainly on the case where the tomographic data are s...
متن کاملTomographic Reconstruction of the Ionospheric Electron Density in term of Wavelets
Ionospheric tomography is a method to investigate the ionospheric electron density in two or three dimensions. In this study, the function-based tomographic technique has been used for regional reconstruction of a 3D tomographic model of the ionospheric electron density using the GPS measurements of the Iranian Permanent GPS Network. Two-dimensional Haar wavelets and empirical orthogonal functi...
متن کاملA moment-based variational approach to tomographic reconstruction
We describe a variational framework for the tomographic reconstruction of an image from the maximum likelihood (ML) estimates of its orthogonal moments. We show how these estimated moments and their (correlated) error statistics can be computed directly, and in a linear fashion from given noisy and possibly sparse projection data. Moreover, thanks to the consistency properties of the Radon tran...
متن کاملOn the shape–from–moments problem and recovering edges from noisy Radon data
Abstract. We consider the problem of reconstructing a planar convex set from noisy observations of its moments. An estimation method based on pointwise recovering of the support function of the set is developed. We study intrinsic accuracy limitations in the shape–from– moments estimation problem by establishing a lower bound on the rate of convergence of the mean squared error. It is shown tha...
