Impact of lossy compression of X-ray projections onto reconstructed tomographic slices.

ABSTRACT: Modern detectors used at synchrotron tomographic microscopy beamlines typically have sensors with more than 4-5 mega-pixels and are capable of acquiring 100-1000 frames per second at full frame. As a consequence, a data rate of a few TB per day can easily be exceeded, reaching peaks of a few tens of TB per day for time-resolved tomographic experiments. This data needs to be post-processed, analysed, stored and possibly transferred, imposing a significant burden onto the IT infrastructure. Compression of tomographic data, as routinely done for diffraction experiments, is therefore highly desirable. This study considers a set of representative datasets and investigates the effect of lossy compression of the original X-ray projections onto the final tomographic reconstructions. It demonstrate
