Encoding probabilistic brain atlases using Bayesian inferenceKoen Van Leemput
Athinoula A Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA
IEEE Trans Med Imaging 28:822-37. 2009..We also present experiments of the proposed atlas construction technique in 3-D, and show the resulting atlases' potential in fully-automated, pulse sequence-adaptive segmentation of 36 neuroanatomical structures in brain MRI scans...
Automated segmentation of hippocampal subfields from ultra-high resolution in vivo MRIKoen Van Leemput
Athinoula A Martinos Center for Biomedical Imaging, Department of Radiology, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA
Hippocampus 19:549-57. 2009..Unlike manual segmentations, our automated technique is fully reproducible, and fast enough to enable routine analysis of the hippocampal subfields in large imaging studies...
Model-based segmentation of hippocampal subfields in ultra-high resolution in vivo MRIKoen Van Leemput
Athinoula A Martinos Center for Biomedical Imaging, Department of Radiology, MGH, Harvard Medical School, USA
Med Image Comput Comput Assist Interv 11:235-43. 2008..We validate the proposed technique by comparing our segmentation results with corresponding manual delineations in ultra-high resolution MRI scans of five individuals...
Asymmetric image-template registrationMert R Sabuncu
Computer Science and Artificial Intelligence Lab, MIT, Harvard Medical School, USA
Med Image Comput Comput Assist Interv 12:565-73. 2009..We instantiate our model within a log-domain diffeomorphic registration framework. Our experiments show exploiting the asymmetry in image-template registration improves alignment in the image coordinates...
The relevance voxel machine (RVoxM): a self-tuning Bayesian model for informative image-based predictionMert R Sabuncu
Athinoula A Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA
IEEE Trans Med Imaging 31:2290-306. 2012..Our results indicate that RVoxM yields biologically meaningful models, while providing state-of-the-art predictive accuracy...
Incorporating parameter uncertainty in Bayesian segmentation models: application to hippocampal subfield volumetryJuan Eugenio Iglesias
Martinos Center for Biomedical Imaging, MGH, Harvard Medical School, USA
Med Image Comput Comput Assist Interv 15:50-7. 2012..As an additional benefit, the method also yields informative "error bars" on the segmentation results for each of the individual sub-structures...
The Relevance Voxel Machine (RVoxM): a Bayesian method for image-based predictionMert R Sabuncu
Athinoula A Martinos Center for Biomedical Imaging, Department of Radiology, MGH, Harvard Medical School, USA
Med Image Comput Comput Assist Interv 14:99-106. 2011..Experiments on age prediction from structural brain MRI indicate that RVoxM yields biologically meaningful models that provide excellent predictive accuracy...
Predicting the location of entorhinal cortex from MRIBruce Fischl
Athinoula A Martinos Center, Department of Radiology, MGH, Harvard Medical School, Charlestown, MA 02129, USA
Neuroimage 47:8-17. 2009....
