Meanwhile the determination of particles with widely differing concentrations is still challenging. In a recent work, we introduced a two-step reconstruction method that tackles this problem by isolating the signal of the lower concentrated tracer for a separate reconstruction. In this work, we adapt the two-step reconstruction method in order to apply a joint reconstruction to the entire signal of all particle concentrations. This is achieved by spatially adaptive Tikhonov regularization. } } @COMMENT{Bibtex file generated on 2024-3-28 with typo3 si_bibtex plugin. Data from https://www.tuhh.de/ibi/people/marija-boberg }
