Radio astronomy aims to image the radio sky with ever-higher resolution and sensitivity. To this end, not only larger telescopes are built, but also novel algorithms for processing the data are developed. This talk focuses on imaging algorithms for producing high-dynamic-range, high-resolution maps of the radio sky. More specifically, I will present RESOLVE, a Bayesian imaging framework. Building state-of-the-art inference algorithms RESOLVE computes an approximate probability distribution over possible sky maps. Thereby, not only high-resolution sky maps but also their uncertainty can be obtained. The algorithmic and computational concepts of RESOLVE are fairly general and applicable also to other fields of data reconstructions.
