Applications of microlocal analysis to some hyperbolic inverse problems
… injectivity and stability of some generalized Radon transforms. Each problem is approached using microlocal methods. In the context of thermoacoustic tomography under the damped wave equation, I show uniqueness and stability of the problem with complete data, provide a reconstruction algorithm …

Multiple suppression in the t-x-p domain
… velocity filters for demultiple operations using Radon transforms traditionally face challenges when the water column is shallow. Additionally, the hyperbolic Radon Transform can be computationally expensive. In this thesis, I introduce a novel multiple suppression technique in the t-x-p domain, …

Seismic-Style Processing of Numerical Em Data
… does not appear to be promising. Linear Radon transforms also detect the reservoir. Standard seismic processing methods are modified to account for the strong frequencydependence of the EM data, in order to focus on the resistivity. Moveout as a function of frequency is replaced by …

Using the Hough transform for analysis of images containing straight lines
… has been shown to be a special case of the Radon transform. As a result, the Hough transform can be inverted using the inverse Radon transform. The Radon transform is important in the medical field, where its inverse, reconstruction from projections, is used to view "slices" through a …
