Correction of motion artifacts is an ongoing and very important task in MRI. This motion, most often introduced by patients that suffer from a medical condition, which makes it difficult to remain motionless during MRI acquisitions, can significantly corrupt the resulting images and their diagnostic value. In this study we show first in-vivo results of our prospective optical motion correction system applied to three-dimensional time of flight (3D TOF) angiography. Results show that compared to the non-motion corrected case the real-time motion correction is able to dramatically improve image quality of 3D TOF angiograms.
