Improved Prospective Optical Motion Correction for DTI Using an Extended-Field-of-View and Self-Encoded Marker

چکیده
INTRODUCTION – Due to the prolonged acquisition time, correction for rigid-body motion artifacts is essential for diagnostic image quality in DTI. Prospective motion correction using a monovision camera system and a checkerboard marker has previously been used to correct for rigid head motion artifacts [1,2]. In this study, we use a more sophisticated marker design to improve prospective optical motion correction in DTI. Improvements over previous work include fast calibration, more accurate motion tracking, and correction of both small and large ranges of head motion.

Self-encoded Marker for Optical Prospective Head Motion Correction in MRI
The tracking and compensation of patient motion during a magnetic resonance imaging (MRI) acquisition is an unsolved problem. For brain MRI, a promising approach recently suggested is to track the patient using an in-bore camera and a checkerboard marker attached to the patient's forehead. However, the possible tracking range of the head pose is limited by the fact that the locally attached mar...
متن کاملImproved Pose Detection for Single Camera Real-Time MR Motion Correction Using a Self-Encoded Marker
INTRODUCTION – Correcting patient motion in MRI is a challenge that is still not fully solved. Although many correction approaches have been suggested, a considerable limitation for the majority of them is that they are only working on a subset of pulse sequences. From a routine clinical imaging perspective this is insufficient. Recently, a new and more promising crop of motion correction metho...
متن کاملSelf-Encoded Marker Design for Adaptive Optical Real-Time Motion Correction
INTRODUCTION – Patient motion during data acquisition is still a challenging problem for many MR sequences and can lead to considerable image artifacts. These often lower diagnostic confidence or even render images non-diagnostic. Recent publications have proposed methods to correct for brain motion by means of tracking the patient pose during the scan and try to adapt for possible changes in r...
متن کاملReal-time optical motion correction for diffusion tensor imaging.
Head motion is a fundamental problem in brain MRI. The problem is further compounded in diffusion tensor imaging because of long acquisition times, and the sensitivity of the tensor computation to even small misregistration. To combat motion artifacts in diffusion tensor imaging, a novel real-time prospective motion correction method was introduced using an in-bore monovision system. The system...
متن کاملBenefits of Optical Prospective Motion Correction for Single-Shot DTI
INTRODUCTION: Involuntary patient motion causes pixel misregistration and changes the effective diffusion-encoding, which, in turn, results in erroneous estimation of diffusion tensors or higher-order variants (1-3). The most common method of motion correction for DTI is retrospective coregistration of diffusionweighted volumes to a reference volume. However, retrospective correction methods ca...
