Gerig, Guido | Spatio-temporal analysis of early brain development | Analysis of human brain development is a crucial step for improved understanding of neurodevelopmental disorders. We focus on normal brain development as is observed in the multimodal longitudinal MRI/DTI data of neonates to two years of age. We present a spatio-temporal analysis framework using Gom... | | 2010-01-01 |

Pascucci, Valerio | Conforming Morse-Smale complexes | Morse-Smale (MS) complexes have been gaining popularity as a tool for feature-driven data analysis and visualization. However, the quality of their geometric embedding and the sole dependence on the input scalar field data can limit their applicability when expressing application-dependent features.... | | 2014-01-01 |

Gerig, Guido | Patient-tailored connectomics visualization for the assessment of white matter atrophy in traumatic brain injury | Available approaches to the investigation of traumatic brain injury (TBI) are frequently hampered, to some extent, by the unsatisfactory abilities of existing methodologies to efficiently define and represent affected structural connectivity and functional mechanisms underlying TI-related pathology.... | | 2012-01-01 |

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 | 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 | Temporal and spatial development of axonal maturation and myelination of white matter in the developing brain | BACKGROUND AND PURPOSE-Diffusion tensor imaging (DTI) has been widely used to investigate the development of white matter (WM). However, information about this development in healthy children younger than 2 years of age is lacking, and most previous studies have only measured fractional anisotropy (... | | 2009-01-01 |

Rosen, Paul Andrew | 2D vector field simplification based on robustness | Vector field simplification aims to reduce the complexity of the flow by removing features in order of their relevance and importance, to reveal prominent behavior and obtain a compact representation for interpretation. Most existing simplification techniques based on the topological skeleton succes... | | 2014-01-01 |

Wunderlich, Adam James | On efficient assessment of image-quality metrics based on linear model observers | This paper is motivated by the problem of image-quality assessment using model observers for the purpose of development and optimization of medical imaging systems. Specifically, we present a study regarding the estimation of the receiver operating characteristic (ROC) curve for the observer and ass... | | 2012-01-01 |

Gerig, Guido | Teasing apart the heterogeneity of autism: Same behavior, different brains in toddlers with fragile X syndrome and autism | To examine brain volumes in substructures associated with the behavioral features of children with FXS compared to children with idiopathic autism and controls. A cross-sectional study of brain substructures was conducted at the first time-point as part of an ongoing longitudinal MRI study of brain ... | | 2009-01-01 |

Pascucci, Valerio | Multivariate volume visualization through dynamic projections | We propose a multivariate volume visualization framework that tightly couples dynamic projections with a high-dimensional transfer function design for interactive volume visualization. We assume that the complex, high-dimensional data in the attribute space can be well-represented through a collecti... | | 2014-01-01 |

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 |

Awate, Suyash Prakash | Multiatlas segmentation as nonparametric regression | This paper proposes a novel theoretical framework to model and analyze the statistical characteristics of a wide range of segmentation methods that incorporate a database of label maps or atlases; such methods are termed as label fusion or multiatlas segmentation.We model these multiatlas segmentati... | | 2014-01-01 |

Gerig, Guido | Toward a comprehensive framework for the spatiotemporal statistical analysis of longitudinal shape data | This paper proposes an original approach for the statistical analysis of longitudinal shape data. The proposed method allows the characterization of typical growth patterns and subject-specific shape changes in repeated time-series observations of several subjects. This can be seen as the extension ... | | 2013-01-01 |
