A Galerkin least squares approach for photoacoustic tomography
Johannes Schwab, Sergiy Pereverzyev, Markus Haltmeier
The development of fast and accurate image reconstruction algorithms is a central aspect of computed tomography. In this paper we address this issue for photoacoustic computed tomo…
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…
Inversion of the attenuated V-line transform for SPECT with Compton cameras
Markus Haltmeier, Sunghwan Moon, Daniela Schiefeneder
The Compton camera is a promising alternative to the Anger camera for imaging gamma radiation, with the potential to significantly increase the sensitivity of SPECT. Two-dimensiona…
Analytic inversion of a conical Radon transform arising in application of Compton cameras on the cylinder
Sunghwan Moon, Markus Haltmeier
Single photon emission computed tomography (SPECT) is a well established clinical tool for functional imaging. A limitation of current SPECT systems is the use of mechanical collim…
The Radon Transform over Cones with Vertices on the Sphere and Orthogonal Axes
Daniela Schiefeneder, Markus Haltmeier
Recovering a function from its integrals over circular cones recently gained significance because of its relevance to novel medical imaging technologies such emission tomography us…
Compressed sensing and sparsity in photoacoustic tomography
Markus Haltmeier, Thomas Berer, Sunghwan Moon +1
Increasing the imaging speed is a central aim in photoacoustic tomography. This issue is especially important in the case of sequential scanning approaches as applied for most exis…
