    Real-Time Signal Processing in Optical Coherence Tomography (OCT) at Fraunhofer IPT

    Optical coherence tomography (OCT) systems are developed at the Fraunhofer Institute for Production Technology (IPT) for medical and industrial applications. OCT is an imaging technique that relies on a signal processing chain. This chain used in Fraunhofer’s OCT systems covers, e.g., the acquisition of data from a line scan camera, image-related adjustments, a Fourier transformation, and the reduction of signal noise. Since these OCT systems are required to provide high spatial and temporal resolution in production setups, e.g., video frame rate (25 frames/s), the parallelization and tuning of the signal processing chain is crucial. more

     

  • Towards Software-Based Real-Time Singles and Coincidence Processing in Positron Emission Tomography (PET) at the Institute for Experimental Molecular Imaging (ExMI)

    For the deployment of novel PET scanners developed in the context of the HYPMED project, the institute for Experimental Molecular Imaging (ExMI) aims at utilizing software-based approaches for its singles and coincidence processing chain. Contrary to current hardware-based implementations, this allows for easier prototyping and the retrieval of raw scanner data, which would otherwise be lost. However, achieving real-time processing throughput becomes a challenge with the increasing data streams of the scanners and the growing complexity of state-of-the-art positioning algorithms. mehr
