A New Sparsification and Reconstruction Strategy for Compressed Sensing Photoacoustic Tomography
Markus Haltmeier, Michael Sandbichler, Thomas Berer +3
Compressed sensing (CS) is a promising approach to reduce the number of measurements in photoacoustic tomography (PAT) while preserving high spatial resolution. This allows to incr…
Compressive Time-of-Flight 3D Imaging Using Block-Structured Sensing Matrices
Stephan Antholzer, Christoph Wolf, Michael Sandbichler +2
Spatially and temporally highly resolved depth information enables numerous applications including human-machine interaction in gaming or safety functions in the automotive industr…
The Averaged Kaczmarz Iteration for Solving Inverse Problems
Housen Li, Markus Haltmeier
We introduce a new iterative regularization method for solving inverse problems that can be written as systems of linear or non-linear equations in Hilbert spaces. The proposed ave…
Operator learning approach for the limited view problem in photoacoustic tomography
Florian Dreier, Sergiy Pereverzyev, Markus Haltmeier
In photoacoustic tomography, one is interested to recover the initial pressure distribution inside a tissue from the corresponding measurements of the induced acoustic wave on the…
Iterative Methods for Photoacoustic Tomography in Attenuating Acoustic Media
Markus Haltmeier, Richard Kowar, Linh V. Nguyen
The development of efficient and accurate reconstruction methods is an important aspect of tomographic imaging. In this article, we address this issue for photoacoustic tomography.…
