Automatic segmentation of neonatal brain mri
- In: MICCAI
, 2004
"... Abstract. This paper describes an automatic tissue segmentation method for neonatal MRI. The analysis and study of neonatal brain MRI is of great interest due to its potential for studying early growth patterns and morphologic change in neurodevelopmental disorders. Automatic segmentation of these i ..."

Texture Analysis of Hippocampus for Epilepsy
- PROCEEDINGS OF SPIE (IMAGE PROCESSING CONFERENCE, AT SPIE MEDICAL IMAGING 2003
, 2003
"... This paper presents our recent study to evaluate how effectively the image texture information within the hippocampus structure can help the physicians to determine the candidates for epilepsy surgery. First we segment the hippocampus from T1-weighted images using our newly developed knowledge-based ..."

A Grid Infrastructure for Image Registration and Segmentation
"... Health care, medical research and drug discovery rely increasingly on the use of computationally intensive image processing algorithms to add value to the wealth of radiological images obtained through techniques such as Magnetic Resonance Imaging (MRI). Use of these algorithms on large cohorts rema ..."

remains problematic given the lack of a suitable IT infrastructure within many institutions and the problems associated with sharing imaging data in a secure and controlled way. Grid computing offers a potential solution to such problems through the promise of large scale distributed resource sharing
Medial Temporal Lobe Activations in fMRI and PET Studies of Episodic Encoding and Retrieval
- Hippocampus
, 1999
"... Early neuroimaging studies often failed to obtain evidence of medial temporal lobe (MTL) activation during episodic encoding or retrieval, but a growing number of studies using functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) have provided such evidence. We rev ..."

, 2006
"... Segmented analysis of subcortical structures within the nonhuman primate can potentially have a profound impact on studying the relationship between volumetric characteristics and alcohol dependencies. Image segmentations have been widely used in quantifying structural information. There are a varie ..."

Hippocampus Segmentation using a Local Prior Model on its Boundary
"... Abstract—Segmentation techniques based on Active Contour Models have been strongly benefited from the use of prior information during their evolution. Shape prior information is captured from a training set and is introduced in the optimization procedure to restrict the evolution into allowable shap ..."
Abstract
- Add to MetaCart
. This paper focuses on a more natural way of incorporating the prior information in the level set framework. For proof of concept the method is applied on hippocampus segmentation in T1-MR images. Hippocampus segmentation is a very challenging task, due to the multivariate surrounding region and the missing
Automated Segmentation of Hippocampal Subfields From Ultra-High Resolution In Vivo MRI
- HIPPOCAMPUS 19:549–557 (2009)
, 2009
"... Recent developments in MRI data acquisition technology are starting to yield images that show anatomical features of the hippocampal formation at an unprecedented level of detail, providing the basis for hippocampal subfield measurement. However, a fundamental bottleneck in MRI studies of the hipp ..."

of the hippocampus at the subfield level is that they currently depend on manual segmentation, a laborious process that severely limits the amount of data that can be analyzed. In this article, we present a computational method for segmenting the hippocampal subfields in ultra-high resolution MRI data in a fully
Materials for an exploratory theory of the network society.
- The British Journal of Sociology
, 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

in this paper: they rely on data and sources presented in the updated version of my trilogy (Castells 2000a). For the sake of clarity, I will rst present the conceptual framework I use in my analysis of social structure. I will then proceed to enumerate the main transformations taking place in social structures
