Interactive Real-Time MRI with BART

The open-source software tool BART provides various state-of-the-art image reconstruction algorithms for MRI. We add an interface for streaming image and k-space data to BART, which should facilitate the application of modern image reconstruction to real-time MRI. Our implementation matches the requirements of interventional MRI in terms of frame rate and latency. Furthermore, we present an intuitive way of interactive slice positioning for MR-guided Interventions using a game controller featuring an inertial measurement unit.
