A wireless accelerometer has been used to measure rotation angles on a dedicated neonatal MRI system. The measured angles have been used to help correct the k-space data to reduce ghosting artifacts. No interference between the accelerometer and the MR system was observed. Some limited improvement in ghosting was found but further work is required on the reconstruction algorithm. The device offers fast temporal resolution (10ms) and no sequence acquisition time overhead as it is a totally independent measurement system.
