Fig. 1From: Evaluating different methods of MR-based motion correction in simultaneous PET/MR using a head phantom moved by a robotic systemSchematic representation of the InnoMotion robotic system. The possible directions of movement are indicated by the coloured arrows. Translational movements were performed along the z-axis and rotations around the x-axis (\(\theta _1\)).
