资源简介:
This data set includes high-resolution (0.5mm) maps of the cerebral cortical surfaces reconstructed from the Colin27 brain atlas [Aubert-Brohe et al., 2006]. The tissue segmentation provided with the atlas was manually edited to merge sub-cortical structures and lateral ventricles with the white matter (WM), then the WM mask was topology-corrected [Bazin et al., 2007] and the WM and cortical gray matter (GM) masks were used to estimate cortical surfaces with the CRUISE algorithm [Han et al., 2004] for the GM/WM boundary (gwb), CSF/GM boundary (cgb), and an average surface (avg) equidistant to both cortical boundaries. Surfaces were reconstructed as levet sets of a signed distance function, and triangular meshes were extracted with the connectivity consistent marching cubes algorithm [Han et al., 2003] and inflated to obtain smooth cortical maps [Tosun et al., 2004]. <br><br>Included here are the left and right cortical segmentations (1=GM, 2=WM), level set surfaces (gwb, cgb, avg) in compressed NIFTI format, and the corresponding extracted and inflated (inf) meshes in VTK ascii format. The NIFTI images are co-aligned with the Colin27 atlas in voxel space, and the surfaces follow the MIPAV mesh space conventions.<br><br>B Aubert-Broche, AC Evans, and DL Collins, “A new improved version of the realistic digital brain phantom,” NeuroImage, vol. 32, no. 1, pp. 138–45, 2006. http://www.ncbi.nlm.nih.gov/pubmed/16750398<br><br>PL Bazin, DL Pham Topology correction of segmented medical images using a fast marching algorithm Computer methods and programs in biomedicine 88 (2), 182-190, 2007<br><br><b>Tosun D</b>, Rettmann ME, Han X, <b>Tao X</b>, Xu C, Resnick SM, Pham DL, Prince JL.

本数据集包含从Colin27脑图谱[Aubert-Brohe等人,2006]重建得到的大脑皮层表面高分辨率(0.5mm)映射图。首先对图谱附带的组织分割结果进行手动编辑:将皮层下结构与侧脑室合并至白质(white matter, WM),随后对白质掩膜进行拓扑校正[Bazin等人,2007];再利用白质与皮层灰质(gray matter, GM)掩膜,通过CRUISE算法[Han等人,2004]估算三类皮层表面:灰质-白质边界(gwb)、脑脊液-灰质边界(cgb),以及与两个皮层边界等距的平均表面(avg)。上述表面以符号距离函数 (signed distance function) 的水平集 (level set) 形式重建,随后通过连通一致性移动立方体 (marching cubes) 算法[Han等人,2003]提取三角网格 (triangular meshes),并经膨胀处理得到平滑的皮层映射图[Tosun等人,2004]。 本数据集包含左右侧皮层分割结果(1代表灰质,2代表白质)、压缩NIFTI格式的水平集表面(gwb、cgb、avg),以及VTK ASCII格式的对应提取与膨胀(inflated, inf)网格。NIFTI图像在体素空间中与Colin27脑图谱对齐,所有表面均遵循MIPAV网格空间规范。 1.
