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.
