X-ray tomography has been proven to be a valuable tool for understanding internal, otherwise invisible, mechanisms in biology and other fields. Recent advances in digital detector technology enabled investigation of dynamic processes in 3D with a temporal resolution down to the milliseconds range. Unfortunately it requires computationally intensive recon- struction algorithms with long post-processing times. We have optimized the reconstruction software employed at the micro-tomography beamlines at KIT and ESRF. Using a 4 stage pipelined architecture and the computational power of modern graphic cards, we were able to reduce the processing time by a factor 75 with a single server. The time required to reconstruct a typical 3D image is reduced down to several seconds only and online visualization is possible for the first time.Copyright is held by the author/owner(s).
