L2 Section, Sample 48. 76 Year Old Female

A 3 mm thick para-sagittal slice of L2 vertebra from an 76 year old female embedded in PMMA then micro-milled block surfaces carbon coated for quantitative 20kV BSE SEM. Later polished to remove coating and then imaged with high-contrast X-Ray Micro-tomography at 90 kV with 30 micron voxel size.本数据集包含一名76岁女性的第2腰椎旁矢状面切片，切片厚度为3 mm。该样本经聚甲基丙烯酸甲酯（PMMA）包埋后，先对其块体表面进行微铣削处理，再实施碳涂层，以开展20kV定量背散射电子扫描电子显微镜（BSE SEM）成像。 随后对样本进行抛光以去除涂层，再以90 kV电压、30微米体素尺寸开展高对比度X射线显微断层扫描（X-Ray Micro-tomography）成像。
