Leader of the group Computational Imaging: Tristan van Leeuwen.


Our research group is developing the next generation of 3D imaging – enabling scientists to look further into objects of all kinds. Based on mathematics, algorithms and numerical solution techniques, our approach is interdisciplinary, combining aspects of mathematics, computer science and physics. We pride ourselves on the versatility of our solutions, and our algorithms can be applied to a wide range of imaging in science, medicine and industry. In Computational Imaging, it’s our goal to constantly push the boundaries of research. By combining advanced image acquisition, parameter estimation, and discrete tomography algorithms for example, we are able to develop workflows for 3D electron microscopy at atomic resolution.

Relating models of nonlinear acoustics through singular limit analysis

Accurate mathematical modeling of nonlinear sound propagation is relevant in various applications of ultrasonic waves, ranging from imaging to lithotripsy and cancer therapy. In this talk, we will discuss how different (non)local PDE models arising in nonlinear acoustics can be related in the limit of relevant small parameters, such as sound diffusivity and thermal relaxation time. In particular, we will quantify the errors made when replacing (singularly) perturbed acoustic models with unperturbed ones. The talk is based on joint works with Barbara Kaltenbacher (University of Klagenfurt) and Mostafa Meliani (Radboud University).
