In this work, we present
a new k-space based approach for position and rotation detection to
improve calibration of optical tracking systems used for prospective
motion correction in MRI. 3D radial acquisition was employed to
detect motion of a custom built phantom. The integrated method was
tested for different motion types and showed a high precision along
with a good robustness for rotation detection.
