Breaking the Resolution limit in Photoacoustic Imaging using Positivity and Sparsity
Peter Burgholzer, Johannes Bauer-Marschallinger, Mike Hettich +1
In this tutorial, we aim to directly recreate some of our "aha" moments when exploring the impact of heat diffusion on the spatial resolution limit of photothermal imaging. Our obj…

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…
