The Fraunhofer EZRT, a division of Fraunhofer IIS, is developing innovative software modules for industrial applications with computed tomography (CT). While standard processes repeatedly reach their limits, these intelligent algorithms help system manufacturers and users to significantly improve the results of three-dimensional imaging and enable the high-precision dimensional measurement for many applications for the first time. The firefly library offers software modules for reconstruction and data improvement for licensing. Beside standard algorithms, like firefly [circle] for classical CT on circular trajectories, we provide several modules for special purposes.
