Exact Series Reconstruction in Photoacoustic Tomography with Circular Integrating Detectors
G. Zangerl, O. Scherzer, M. Haltmeier
A method for photoacoustic tomography is presented that uses circular integrals of the acoustic wave for the reconstruction of a three-dimensional image. Image reconstruction is a…

On Steepest-Descent-Kaczmarz Methods for Regularizing Systems of Nonlinear Ill-posed Equations
A. De Cezaro, M. Haltmeier, A. Leitao +1
We investigate modified steepest descent methods coupled with a loping Kaczmarz strategy for obtaining stable solutions of nonlinear systems of ill-posed operator equations. We sho…
