1 Hall, Eric S.Aiding clinicians through summarization of perinatal dataExploratory analysis has focused on developing summarized views of monitor-captured perinatal data to support adherence to established clinical protocols. In addition to facilitating rapid access to significant clinical trends and reducing subjective interpretation of monitor-captured data, combini...Perinatal data; Perinatal care; Trapeze Interactive Poster2009-09-23
2 Frey, Lewis J.Enhancing caBIG™ workflow for multi-tier distributionIntroduction caBIG™ Integration caBIG™ provides a GRID based application environment with data abstraction and vocabulary services, workflow management and a security framework. Sensor Abstraction Interface It is proposed to provide a sensor abstraction interface, using caDSR, enabling caBIG...caBIG; Sensor abstraction interface; Multi-tier distribution; Trapeze Interactive Poster2009
3 Gerig, GuidoParticle based shape regression of open surfaces with applications to developmental neuroimagingShape regression promises to be an important tool to study the relationship between anatomy and underlying clinical or biological parameters, such as age. In this paper we propose a new method to building shape models that incorporates regression analysis in the process of optimizing correspondences...2009-01-01
4 Gerig, GuidoEvaluation of brain MRI alignment with the Robust Hausdorff Distance MeasuresWe present a novel automated method for assessment of image alignment, applied to non-rigid registration of brain Magnetic Resonance Imaging data (MRI) for image-guided neurosurgery. We propose a number of robust modifications to the Hausdorff distance (HD) metric, and apply it to the edges recovere...Magnetic resonance imaging (MRI)2008-01-01
5 Gerig, GuidoSimulation of brain tumors in MR images for evaluation of segmentation efficacy.Obtaining validation data and comparison metrics for segmentation of magnetic resonance images (MRI) are difficult tasks due to the lack of reliable ground truth. This problem is even more evident for images presenting pathology, which can both alter tissue appearance through infiltration and cause ...Brain MRI; Segmentation validation; Tumor simulation; Simulation of tumor infiltration; Diffusion tensor imaging; Ground truth; Gold standard2009-01-01
6 Hawkes, KristenAffluent hunters? Some comments in light of the Alyawara caseOur recent analysis (O'Connell and Hawkes in press) of plant food collecting among the Alyawara, a central Australian hunting group, shows that the cost of subsistence is sometimes quite high, far higher than the current conven. tional wisdom regarding hunters would suggest. We infer from available ...1981-01-01
7 Gerig, GuidoBrain lesion segmentation through physical model estimationSegmentations of brain lesions from Magnetic Resonance (MR) images is crucial for quantitative analysis of lesion populations in neuroimaging of neurological disorders. We propose a new method for segmenting lesions in brain MRI by inferring the underlying physical models for pathology. We use the r...Magnetic resonance (MR) images; Neurological disorders; Diffusion tensor imaging (DTI).2008-01-01
8 Hawkes, KristenEvaluating grandmother effectsWomen who have outlived child-bearing have long been described as post-reproductive. But contributions they make to the survival or fertility of their descendants enhance the reproduction of their genes. Consequently natural selection affects this characteristic stage of human life history. Grandmot...Human life history; Historical demography; Human longevity2009-01-01
9 Gerig, GuidoSpatiotemporal atlas estimation for developmental delay detection in longitudinal datasetsWe propose a new methodology to analyze the anatomical variability of a set of longitudinal data (population scanned at several ages). This method accounts not only for the usual 3D anatomical variability (geometry of structures), but also for possible changes in the dynamics of evolution of the str...2009-01-01
10 Hawkes, KristenMortality and fertility rates in humans and chimpanzees: how within-species variation complicates cross-species comparisonsA grandmother hypothesis may explain why humans evolved greater longevity while continuing to end female fertility at about the same age as do the other great apes. With that grandmother hypothesis in mind, we sought to compare age-specific mortality and fertility rates between humans and chimpanzee...2009-01-01
11 Hawkes, KristenKin selection and cultureThis paper argues that while the discriminations organizing human action are cultural, and kinship in anthropology is not equivalent to genetic relatedness, the theory of kin selection developed in evolutionary biology can tell us a great deal about human social organization. Data on garden assistan...1983-01-01
12 Gerig, GuidoAbnormal brain synchrony in down syndromeDown Syndrome is the most common genetic cause for intellectual disability, yet the pathophysiology of cognitive impairment in Down Syndrome is unknown. We compared fMRI scans of 15 individuals with Down Syndrome to 14 typically developing control subjects while they viewed 50 min of cartoon video c...2013-01-01
13 Gerig, GuidoProbabilistic white matter fiber tracking using, particle filtering and von mises-fisher samplingStandard particle filtering technique have previously been applied to the problem of fiber tracking by Brun et al. (2002) and Bjornemo et al. (2002). However, these previous attempts have not utilised the full power of the technique, and as a result the fiber paths were tracked in a goal directed wa...Diffusion tensor MRI; Tractography; Probabilistic fiber tracking; Particle filtering; von Mises-Fisher sampling2009-01-01
14 Gerig, GuidoNetwork inefficiencies in autism spectrum disorder at 24 monthsAutism spectrum disorder (ASD) is a developmental disorder defined by behavioral symptoms that emerge during the first years of life. Associated with these symptoms are differences in the structure of a wide array of brain regions, and in the connectivity between these regions. However, the use of c...2014-01-01
15 Gerig, GuidoQuantitative tract-based white matter development from birth to age 2 yearsFew large-scale studies have been done to characterize the normal human brain white matter growth in the first years of life. We investigated white matter maturation patterns in major fiber pathways in a large cohort of healthy young children from birth to age two using diffusion parameters fraction...White matter maturation; Axonal myelination; Early brain development; Diffusion properties; DTI atlas; Fiber tracking; Functional regression analysis2012-01-01
16 Gerig, GuidoDiffusion imaging quality control via entropy of principal direction distributionDiffusion MR imaging has received increasing attention in the neuroimaging community, as it yields new insights into the microstructural organization of white matter that are not available with conventional MRI techniques. While the technology has enormous potential, diffusion MRI suffers from a uni...Diffusion magnetic resonance imaging; Diffusion tensor imaging; Quality assessment; Entropy2013-01-01
