Impact of lossy compression of X-ray projections onto reconstructed tomographic slices
Synchrotron beamlines acquiring data for tomographic imaging routinely produce a few TB of data per day, and significantly more in the case of time-resolved studies. This work investigates the impact of lossy compression of raw acquisitions onto tomographic reconstructions, aiming for production use. It is shown that a compression factor of at least three to four times does generally not affect the reconstruction quality and that higher factors (six to eight times) can be achieved for tomographic volumes with a high signal-to-noise ratio as it is the case for phase-retrieved datasets.
