Atlas-Guided Segmentation of Vervet Monkey Brain MRI

The vervet monkey is an important nonhuman primate model that allows the study of isolated environmental factors in a controlled environment. Analysis of monkey MRI often suffers from lower quality images compared with human MRI because clinical equipment is typically used to image the smaller monkey brain and higher spatial resolution is required. This, together with the anatomical differences...

Statistical atlas-based sub-voxel segmentation of 3D brain MRI

We present a 3D brain MRI segmentation method in which a high resolution label image evolves under the influence of multiple constraints. The constraints are expressed in a versatile energy minimization framework which allows for evolutions only at label boundaries, effectively making it a surface evolution system. Constraints are defined using atlas-mapped parameters. The atlas, composed of a ...

Multi-Atlas Brain MRI Segmentation with Multiway Cut

Characterization of anatomical structure of the brain and efficient algorithms for automatically analyzing brain MRI have gained an increasing interest in recent years. In this paper, we propose an algorithm that automatically segments the anatomical structures of magnetic resonance human brain images. Our method uses the prior knowledge of labels given by experts to statistically investigate t...

The Impact of Atlas Formation Methods on Atlas-Guided Brain Segmentation

We analyze the impact of atlas construction within the context of an atlas-guided segmenter applied to a morphometry study in neuroanatomy. Automatic segmenters often rely on anatomical information encoded via probabilistic atlases. These atlases are frequently constructed by registering collections of training data. In this paper, we study the impact of registration methods as well as the trai...

Interactive surface-guided segmentation of brain MRI data

MRI segmentation is a process of deriving semantic information from volume data. For brain MRI data, segmentation is initially performed at a voxel level and then continued at a brain surface level by generating its approximation. While successful most of the time, automated brain segmentation may leave errors which have to be removed interactively by editing individual 2D slices. We propose an...
