A Variational Reconstruction Method for Undersampled Dynamic X-ray Tomography based on Physical Motion Models
Martin Burger, Hendrik Dirks, Lena Frerking +3
In this paper we study the reconstruction of moving object densities from undersampled dynamic X-ray tomography in two dimensions. A particular motivation of this study is to use r…

Controlled Wavelet Domain Sparsity in X-ray Tomography
Zenith Purisha, Juho Rimpeläinen, Tatiana Bubba +1
Tomographic reconstruction is an ill-posed inverse problem that calls for regularization. One possibility is to require sparsity of the unknown in an orthonormal wavelet basis. Thi…
