Robust and Fast Evaluation of Orbital Navigator Data for Rigid Body Motion Estimation
نویسندگان
چکیده
Introduction Motion during image acquisition can cause serious image artifacts. To overcome this problem the use of navigator signals ([1-3]) has been proposed combined with either realtime correction of the data acquisition or motion compensated reconstruction. The quality of the correction depends critically on the estimated motion derived from the navigator signal. Here, we present a fast, robust and precise algorithm to evaluate data from an orbital navigator trajectory and its application to motion compensated reconstruction.

Novel Motion Correction Technique Using Orbital Navigator Echoes in Interleaved Spiral Imaging
Spiral imaging does not produce apparent flow artifacts. However, it remains sensitive to rapid rigid body motion. In this abstract, a motion correction technique using an orbital navigator “ring” in interleaved spiral imaging is presented. In this technique, a circular k-space trajectory is incorporated into each spiral interleaf. Data inconsistency due to both rotation and translation can be ...
متن کاملCombination of Motion Adapted Gating with Non-Rigid Motion Correction for Free-Breathing MRI
Introduction The navigator gating technique reduced respiratory motion artifacts and is suited to abdominal MRI with patients who have difficulty in breath-holding. The motion adapted gating (MAG) approach [1] employs varying gating threshold depending on phase encoding steps, which accelerates gating to reduce scan time. However, even the MAG approach results in considerably longer scan time c...

متن کاملRobust state estimation in power systems using pre-filtering measurement data
State estimation is the foundation of any control and decision making in power networks. The first requirement for a secure network is a precise and safe state estimator in order to make decisions based on accurate knowledge of the network status. This paper introduces a new estimator which is able to detect bad data with few calculations without need for repetitions and estimation residual cal...
