Automatic Segmentation of Brain Tissues and MR Bias Field Correction Using a Cigital Brain Atlas
نویسندگان
چکیده
This paper 1 proposes a method for fully automatic segmen-tation of brain tissues and MR bias eld correction using a digital brain atlas. We have extended the EM segmentation algorithm, including an explicit parametric model of the bias eld. The algorithm interleaves classiication with parameter estimation, yielding better results at every iteration. The method can handle multi-channel data and slice-per-slice constant oosets, and is fully automatic due to the use of a digital brain atlas.

Quantitative 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 ...
