Farrell, Timothy W. | Organizational culture associated with provider satisfaction | Background: Organizational culture is key to the successful implementation of major improvement strategies. Transformation to a patient-centered medical home (PCHM) is such an improvement strategy, requiring a shift from provider-centric care to team-based care. Because this shift may impact provide... | | 2014-01-01 |

Gerig, Guido | Parametric regression scheme for distributions: analysis of DTI fiber tract diffusion changes in early Brain Development | Temporal modeling frameworks often operate on scalar variables by summarizing data at initial stages as statistical summaries of the underlying distributions. For instance, DTI analysis often employs summary statistics, like mean, for regions of interest and properties along fiber tracts for populat... | | 2014-01-01 |

Kuhlman, Brian | PHD Entrepreneur | The idea for this speech began when my friends and family started asking what I would do after graduating with my PhD in psychology. Folks tended to get a bit confused when I replied that my plan is to start a business. You don't need a PhD to do that! It's true. The path leading from PhD to Entrepr... | entrepreneur; PhD; doctoral; industry; academia | 2013-05-03 |

Gerig, Guido | Prenatal mild ventriculomegaly predicts abnormal development of the neonatal brain | Background: Many psychiatric and neurodevelopmental disorders are associated with mild enlargement of the lateral ventricles thought to have origins in prenatal brain development. Little is known about development of the lateral ventricles and the relationship of prenatal lateral ventricle enlargeme... | | 2008-01-01 |

Gerig, Guido | Quality control of diffusion weighted images | Diffusion Tensor Imaging (DTI) has become an important MRI procedure to investigate the integrity of white matter in brain in vivo. DTI is estimated from a series of acquired Diffusion Weighted Imaging (DWI) volumes. DWI data suffers from inherent low SNR, overall long scanning time of multiple dire... | | 2010-01-01 |

Gerig, Guido | Quantifying regional growth patterns through longitudinal analysis of distances between multimodal MR intensity distributions | Quantitative analysis of early brain development through imaging is critical for identifying pathological development, which may in turn affect treatment procedures. We propose a framework for analyzing spatiotemporal patterns of brain maturation by quantifying intensity changes in longitudinal MR i... | | 2012-01-01 |

Gerig, Guido | Reduced relationship to cortical white matter volume revealed by Tractography-based segmentation of the corpus callosum in young children with developmental delay | Objective: The corpus callosum is the primary anatomical substrate for inter-hemispheric communication, which is important for a range of adaptive and cognitive behaviors in early development. Previous studies that have measured the corpus callosum in developmental populations have been limited by t... | | 2006-01-01 |

Gerig, Guido | Regional gray matter growth, sexual dimorphism, and cerebral asymmetry in the Neonatal Brain | Although there has been recent interest in the study of childhood and adolescent brain development, very little is known about normal brain development in the first few months of life. In older children, there are regional differences in cortical gray matter development, whereas cortical gray and wh... | | 2007-01-01 |

Gerig, Guido | Segmentation of serial MRI of TBI patients using personalized atlas construction and topological change estimation | Traumatic brain injury (TBI) due to falls, car accidents, and warfare affects millions of people annually. Determining personalized therapy and assessment of treatment efficacy can substantially benefit from longitudinal (4D) magnetic resonance imaging (MRI). In this paper, we propose a method for s... | | 2012-01-01 |

Gerig, Guido | Semi-automated application for kidney motion correction and filtration analysis in MR renography | Altered renal function commonly affects patients with cirrhosis, a consequence of chronic liver disease. From lowdose contrast material-enhanced magnetic resonance (MR) renography, we can estimate the Glomerular Filtration Rate (GFR), an important parameter to assess renal function. Two-dimensional ... | | 2014-01-01 |

Macleod, Robert S. | Sensitivity of epicardial electrical markers to acute ischemia detection | Introduction: We hypothesize that electrocardiographic measurements from the intramyocardial space contain more sensitive markers of ischemia than those detectable on the epicardium. The goal of this study was to evaluate different electrical markers for their potential to detect the earliest phases... | | 2014-01-01 |

Gerig, Guido | Spatial intensity prior correction for tissue segmentation in the developing human brain | The degree of white matter (WM) myelination is rather inhomogeneous across the brain. As a consequence, white matter appears differently across the cortical lobes in MR images acquired during early postnatal development. At 1 year old specifically, the gray/white matter contrast of MR images in pref... | | 2011-01-01 |
