Bootstrapping fully-automatic temporal fetal brain segmentation in volumetric MRI time series
… training data for the task of segmenting fetal brains in volumetric MRI time series data. Temporal analysis of MRI images requires accurate segmentation across frames, despite large amounts of unpredictable motion. We use the predicted segmentations of a baseline model and leverage anatomical …

Brain segmentation using endogenous contrast mechanism using breath holding fMRI signal for tissue characterization
… for the analysis of the complexity of the human brain. MRJ is a non-invasive method and gives high spatial resolution maps of the brain with soft tissue contrast. Conventional MRI technique modified to be used to image the functionality at high temporal resolution is known as fMRI. In fMRI the …

Automatic segmentation of magnetic resonance images of the brain
… distance between slices being a few millimeters. Brain segmentation is the delineation of one or more anatomical structures within images of the brain. It promotes greater understanding of spatial relationships to aid in such tasks as surgical planning and clinical diagnoses, particularly when the …

3 Tesla Magnetic Resonance Imaging of Hippocampal Asymmetry: Results from the Dallas Heart Study
… were analyzed using two standard automated brain segmentation programs, FSL-FIRST and Freesurfer. Individuals with imaging error, self-reported stroke, or major structural abnormalities were excluded. Statistical analyses were performed to determine significance of the findings across age, …

From Discrete to Continuous: Learning 3D Geometry from Unstructured Points by Random Continuous Space Queries
… problems in medical image registration and segmentation. Specifically, our network is adapted and applied to two different, traditionally challenging problems: 1) liver image-to-physical registration; and 2) tumour-bearing whole brain segmentation. In both of these tasks, significant …
