We present a digital phantom intended for MR-guided radiotherapy imaging sequence design and testing. The framework uses existing phantom generating software to provide the anatomical shape and movement, while the MRI simulation is handled by a modified version of a Bloch simulator. The accuracy of the phantom framework was demonstrated by simulating a 4D image of a single respiratory cycle and also by reproducing motion-related artefacts in a 2D image.
