PET and MRI provide complementary information in the study of the human brain.
Simultaneous PET/MRI data acquisition allows the spatial and temporal correlation of the …

Head motion is difficult to avoid in long PET studies, degrading the image quality and
offsetting the benefit of using a high-resolution scanner. As a potential solution in an …

Purpose: Motion correction in PET has become more important as system resolution has
improved. The purpose of this study was to evaluate the accuracy of event‐by‐event and …

We present a system for head motion tracking in 3D brain imaging. The system is based on
facial surface reconstruction and tracking using a structured light (SL) scanning principle …

Recent advancements in high resolution Positron Emission Tomography (PET) have made it
possible to study metabolic activity and the anatomy of the brain in great details. It becomes …

Purpose To compare prospective motion correction (PMC) and retrospective motion
correction (RMC) in Cartesian 3D‐encoded MPRAGE scans and to investigate the effects of …

Head motion during MR acquisition reduces image quality and has been shown to bias
neuromorphometric analysis. The quantification of head motion, therefore, has both …

The recent availability of dynamic, dense, and low-cost range imaging has gained
widespread interest in health care. It opens up new opportunities and has an increasing …

Objective We demonstrate and evaluate the first markerless motion tracker compatible with
PET, MRI, and simultaneous PET/MRI systems for motion correction (MC) of brain imaging …

Neuroimaging has an essential role in studies of brain health and of cerebrovascular and
neurodegenerative diseases, requiring the availability of versatile magnetic resonance …
