Functional connectivity MRI quality control procedures in CONN [PDF]

open access: yesFrontiers in Neuroscience, 2023
Quality control (QC) for functional connectivity magnetic resonance imaging (FC-MRI) is critical to ensure the validity of neuroimaging studies. Noise confounds are common in MRI data and, if not accounted for, may introduce biases in functional measures

Evidence-based guideline implementation of quality assurance and quality control procedures in the Saudi National Mental Health Survey [PDF]

open access: yesInt J Ment Health Syst, 2017
BackgroundThe World Mental Health surveys have been known to apply high standards of quality control, but few studies have been published to document this. Furthermore, the effectiveness of quality control has rarely been reported in the Middle East.Case

Trajectories of cortical thickness maturation in normal brain development – The importance of quality control procedures [PDF]

open access: yesNeuroimage, 2015
Several reports have described cortical thickness (CTh) developmental trajectories, with conflicting results. Some studies have reported inverted-U shape curves with peaks of CTh in late childhood to adolescence, while others suggested predominant ...

Quality control procedures and metrics for resting-state functional MRI [PDF]

open access: yesFrontiers in Neuroimaging, 2023
The monitoring and assessment of data quality is an essential step in the acquisition and analysis of functional MRI (fMRI) data. Ideally data quality monitoring is performed while the data are being acquired and the subject is still in the MRI scanner ...

Marker-less real-time intra-operative camera and hand-eye calibration procedure for surgical augmented reality

open access: yesHealthcare Technology Letters, 2019
Accurate medical Augmented Reality (AR) rendering requires two calibrations, a camera intrinsic matrix estimation and a hand-eye transformation. We present a unified, practical, marker-less, real-time system to estimate both these transformations during ...
