I have developed an accelerated sparse time-invariant Radon transform (RT) in the mixed frequency-time domain based on iterative 2D model shrinkage time domain. denote it as SRTIS. In traditional RT domain, is modeled a inverse problem that solved by iteratively reweighted least-squares (IRLS) algorithm and forward RTs are implemented frequency this method, IRLS replaced shrinkage, i.e., sparsity of promoted some simple operations Synthetic real data demultiple examples using parabolic given to demonstrate better performance SRTIS when compared with least-squares-based RT, time-domain
