101 Macleod, Robert S.Identification and acute targeting of gaps in atrial ablation lesion sets using a real-time magnetic resonance imaging systemBackground-Radiofrequency ablation is routinely used to treat cardiac arrhythmias, but gaps remain in ablation lesion sets because there is no direct visualization of ablation-related changes. In this study, we acutely identify and target gaps using a real-time magnetic resonance imaging (RT-MRI) sy...2012-01-01
102 Seyedhosseini Tarzjani, Seyed MojtabaImage segmentation with cascaded hierarchical models and logistic disjunctive normal networksContextual information plays an important role in solving vision problems such as image segmentation. However, extracting contextual information and using it in an effective way remains a difficult problem. To address this challenge, we propose a multi-resolution contextual framework, called cascade...2013-01-01
103 Gur, YanivGraph diffusion distance: a difference measure for weighted graphs based on the graph Laplacian exponential kernelWe propose a novel difference metric, called the graph diffusion distance (GDD), for quantifying the difference between two weighted graphs with the same number of vertices. Our approach is based on measuring the average similarity of heat diffusion on each graph. We compute the graph Laplacian expo...2013-01-01
104 Gerig, GuidoMulti-atlas segmentation of subcortical brain structures via the AutoSeg software pipelineAutomated segmenting and labeling of individual brain anatomical regions, in MRI are challenging, due to the issue of individual structural variability. Although atlas-based segmentation has show its potential for both tissue and structure segmentation, due to the inherent natural variability as wel...2014-01-01
105 Anderson, Erik WesleyDiscovering and visualizing patterns in EEG dataBrain activity data is often collected through the use of electroen-cephalography (EEG). In this data acquisition modality, the electric fields generated by neurons are measured at the scalp. Although this technology is capable of measuring activity from a group of neurons, recent efforts provide ev...2013-01-01
106 Kuhlman, BrianPHD EntrepreneurThe 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; academia2013-05-03
107 Wunderlich, Adam JamesA nonparametric procedure for comparing the areas under correlated LROC curvesIn contrast to the receiver operating characteristic (ROC) assessment paradigm, localization ROC (LROC) analysis provides a means to jointly assess the accuracy of localization and detection in an observer study. In a typical multireader, multicase (MRMC) evaluation, the data sets are paired so that...2012-01-01
108 Wunderlich, Adam JamesOn efficient assessment of image-quality metrics based on linear model observersThis 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
