Digital Reference Objects with BART

Digital Reference Objects (DRO) are important for developing imaging and reconstruction techniques especially in medical imaging applications. They allow a stepwise increase in complexity during testing of methods by simulating reproducible datasets. In this work we present a variety of tools the BART toolbox provides for the creation and simulation of DROs. We present a workflow for designing DROs with Bézier curves using vector graphics applications which are then imported into BART. Furthermore, we show simulation of analytical k-space data with 2D and 3D coil sensitivities and combining them with simulated signal curves to obtain k-space data for complex scenarios.
