A low-cost rotation device was designed and built to enable remotely controllable phantom movements. With the device, motions are highly reproducible. For cross-calibrations of external tracking systems, it prevents table movement or the need to move the phantom by hand from inside the scanner during the calibration, reduces the overall calibration duration, and provides similar calibration performance compared to the freehand approach performed by an expert. The CAD model was made publically available.
