Analysis for Full Field Photoacoustic Tomography with Variable Sound Speed
Linh V. Nguyen, Markus Haltmeier, Richard Kowar +1
Photoacoustic tomography (PAT) is a non-invasive imaging modality that requires recovering the initial data of the wave equation from certain measurements of the solution outside t…
Reconstruction algorithms for photoacoustic tomography in heterogenous damping media
Linh V. Nguyen, Markus Haltmeier
In this article, we study several reconstruction methods for the inverse source problem of photoacoustic tomography (PAT) with spatially variable sound speed and damping. The backb…
Time reversal method for thermoacoustic acoustic tomography in elastic media: convergence with sharp observation time
Vitaly Katsnelson, Linh V. Nguyen
In this article, we consider the inverse source problem arising in photoacoustic tomography in elastic media. We show that the time reversal method, proposed by Tittelfitz [Inverse…
Analysis of the Linearized Problem of Quantitative Photoacoustic Tomography
Markus Haltmeier, Lukas Neumann, Linh V. Nguyen +1
Quantitative image reconstruction in photoacoustic tomography requires the solution of a coupled physics inverse problem involvier light transport and acoustic wave propagation. In…
Analysis of Iterative Methods in Photoacoustic Tomography with Variable Sound Speed
Markus Haltmeier, Linh V. Nguyen
In this article, we revisit iterative methods for solving the inverse problem of photoacoustic tomography in free space. Recently, there have been interesting developments on expli…
On Artifacts in Limited Data Spherical Radon Transform: Curved Observation Surface
Lyudmyla L. Barannyk, Jürgen Frikel, Linh V. Nguyen
In this article, we consider the limited data problem for spherical mean transform. We characterize the generation and strength of the artifacts in a reconstruction formula. In con…
