L2 Section, Sample 38. 68 Year Old Female

A 3 mm thick para-sagittal slice of L2 vertebra from an 68 year old female embedded in PMMA then micro-milled block surfaces carbon coated for quantitative 20kV BSE SEM.<br><br>Later polished to remove coating and then imaged with high-contrast X-Ray Micro-tomography at 90 kV with 30 micron voxel size.取自68岁女性的第2腰椎（L2 vertebra）3毫米厚旁矢状面切片，经聚甲基丙烯酸甲酯（PMMA）包埋并制备为微铣削块体后，对块体表面实施碳涂层处理，用于20kV背散射扫描电子显微镜（BSE SEM）的定量成像。 后续经抛光处理以去除涂层，随后以90kV电压、30微米体素尺寸开展高对比度X射线显微断层成像（X-Ray Micro-tomography）。
