L2 Section, Sample 33. 67 Year Old Female

A 3 mm thick para-sagittal slice of L2 vertebra from an 67 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.

本数据集样本为一名67岁女性的L2椎体旁矢状面切片，厚度为3毫米。该样本经聚甲基丙烯酸甲酯（PMMA）包埋后进行微铣削加工，随后对块体表面实施碳涂层处理，以用于20kV定量背散射扫描电子显微镜（BSE SEM）检测。后续经抛光去除涂层后，以90kV电压、30微米体素尺寸完成高对比度X射线显微断层扫描（X-Ray Micro-tomography）成像。
