Spatiotemporal Morphometry of Adjacent Tissue Layers with Application to the Study of Sulcal Formation
The process of brain growth involves the expansion of tissue at different rates at different points within the brain. As the layers within the develo** brain evolve they can thicken or increase in area as th...

A Spatio-temporal Atlas of the Human Fetal Brain with Application to Tissue Segmentation
Modeling and analysis of MR images of the early develo** human brain is a challenge because of the transient nature of different tissue classes during brain growth. To address this issue, a statistical model...

Atlas-Based Segmentation of the Germinal Matrix from in Utero Clinical MRI of the Fetal Brain
Recently developed techniques for reconstruction of high-resolution 3D images from fetal MR scans allows us to study the morphometry of develo** brain tissues in utero. However, existing adult brain analysis...

Incorporating DTI Data as a Constraint in Deformation Tensor Morphometry Between T1 MR Images
Deformation tensor morphometry provides a sensitive approach to detecting and map** subtle volume changes in the brain from conventional high resolution T1W MRI data. However, it is limited in its ability to...

Population Based Analysis of Directional Information in Serial Deformation Tensor Morphometry
Deformation morphometry provides a sensitive approach to detecting and map** subtle volume changes in the brain. Population based analyses of this data have been used successfully to detect characteristic ch...

A System for Measuring Regional Surface Folding of the Neonatal Brain from MRI
This paper describes a novel approach to in-vivo measurement of brain surface folding in clinically acquired neonatal MR image data, which allows evaluation of surface curvature within subregions of the cortex...

Co-analysis of Maps of Atrophy Rate and Atrophy State in Neurodegeneration
The variability in atrophy rate in patients with neurodegenerative disease can be partially explained by disease stage. Since atrophy state (baseline scan tissue volume) correlates with cognitive impairment an...

Steps Toward a Stereo-Camera-Guided Biomechanical Model for Brain Shift Compensation
Surgical navigation systems provide the surgeon with a display of preoperative and intraoperative data in the same coordinate system. However, the systems currently in use in neurosurgery are subject to inaccu...
