A Re-defined and Generalized Percent-Overlap-of-Activation Measure for Studies of fMRI Reproducibility and its Use in Identifying Outlier Activation Maps
Ranjan Maitra
Functional Magnetic Resonance Imaging~(fMRI) is a popular non-invasive modality to investigate activation in the human brain. The end result of most fMRI experiments is an activati…
Assessing Certainty of Activation or Inactivation in Test-Retest fMRI Studies
Ranjan Maitra
Functional Magnetic Resonance Imaging~(fMRI) is widely used to study activation in the human brain. In most cases, data are commonly used to construct activation maps corresponding…
Fracture Mechanics-Based Quantitative Matching of Forensic Evidence Fragments
Geoffrey Z. Thompson, Bishoy Dawood, Tianyu Yu +5
Fractured metal fragments with rough and irregular surfaces are often found at crime scenes. Current forensic practice visually inspects the complex jagged trajectory of fractured…
Fast matrix-free methods for model-based personalized synthetic MR imaging
Subrata Pal, Somak Dutta, Ranjan Maitra
Synthetic Magnetic Resonance (MR) imaging predicts images at new design parameter settings from a few observed MR scans. Model-based methods, that use both the physical and statist…
A practical model-based segmentation approach for improved activation detection in single-subject functional Magnetic Resonance Imaging studies
Wei-Chen Chen, Ranjan Maitra
Functional Magnetic Resonance Imaging (fMRI) maps cerebral activation in response to stimuli but this activation is often difficult to detect, especially in low-signal contexts and…
A nonstationary nonparametric Bayesian approach to dynamically modeling effective connectivity in functional magnetic resonance imaging experiments
Sourabh Bhattacharya, Ranjan Maitra
Effective connectivity analysis provides an understanding of the functional organization of the brain by studying how activated regions influence one other. We propose a nonparamet…
