چکیده
M. Seitel, S. Suja, R. Mullick Image Technologies Lab, GE India Technology Centre, Bangalore, Karnataka, India Purpose The lateral ventricles are major cavities in the top section of the human brain filled with cerebrospinal fluid (CSF). Some brain diseases cause change in shape and size of the lateral ventricles. The advancement of Alzheimer’s disease (AD), for instance, is assumed to affect the hippocampus, and thus to indirectly influence the adjacent temporal horns, which are a part of the ventricular system. Manual delineation of regions of interest is time-consuming and error-prone. In this paper we are proposing a semi-automatic procedure for segmenting the lateral ventricles from human brain MR volumes. With the long-term objective of a comprehensive study of AD, particular importance is given to the inclusion of the temporal horns in the segmentation process.

Automatic segmentation of the ventricular system from MR images of the human brain.
An algorithm was developed that automatically segments the lateral and third ventricles from T1-weighted 3-D-FFE MR images of the human brain. The algorithm is based upon region-growing and mathematical morphology operators and starts from a coarse binary total brain segmentation, which is obtained from the 3-D-FFE image. Anatomical knowledge of the ventricular system has been incorporated into...
متن کاملQuantitative Comparison of SPM, FSL, and Brainsuite for Brain MR Image Segmentation
Background: Accurate brain tissue segmentation from magnetic resonance (MR) images is an important step in analysis of cerebral images. There are software packages which are used for brain segmentation. These packages usually contain a set of skull stripping, intensity non-uniformity (bias) correction and segmentation routines. Thus, assessment of the quality of the segmented gray matter (GM), ...

Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...
متن کاملAutomatic hippocampus segmentation of 7.0 Tesla MR images by combining multiple atlases and auto-context models
In many neuroscience and clinical studies, accurate measurement of hippocampus is very important to reveal the inter-subject anatomical differences or the subtle intra-subject longitudinal changes due to aging or dementia. Although many automatic segmentation methods have been developed, their performances are still challenged by the poor image contrast of hippocampus in the MR images acquired ...

Segmentation of anatomic structures of the human brain from Magnetic Resonance (MR) images is important for assessing treatment efficacy, screening for anomalies, and improving our understanding of human development. The labor-intensive nature of manual segmentation, however, makes such a technique viable only in selected cases. In this paper, we present a new approach to segmentation that invo...
