µCT scan: Phyllium letiranti female head and thorax (Phasmatodea: Phylliidae)
收藏资源简介:
CT data Phyllium letiranti female, head and thorax. We used the EasyTom μ-CT system (RX Solutions, France) at the Institute for X-Ray Physics, Göttingen, Germany, equipped with a sealed X-ray tube (Hamamatsu L12161-07) that utilizes a tungsten (W) target, offering a spot size of 5 μm in small focal spot mode. We utilized a CCD detector (Gadox-scintillator) with a pixel size of 9x9 μm², employing 2x2 binning for capturing projection images. To ensure optimal imaging for each individual specimen, we adjusted several parameters. For data processing, the acquired data underwent reconstruction using the software provided with the instrument. tube voltage (kV): 80 geometric magnification: 4 voxel size (µm): 4.47 number of acquisition angles: 1568 accumulation time (s): 4 total scan time (h) (+-10min): 2.6 acquisition time per angle: 2x2s number of turns: 2 overhead in %: 49.2 detector pixelsize (µm): 18 source-object-distance (mm): 30.5 source-detector-distance (mm): 122.7
CT数据集:丽亭叶䗛(Phyllium letiranti)雌性个体的头部与胸部。 本实验使用德国哥廷根X射线物理研究所的EasyTom μ-CT(显微CT)系统(法国RX Solutions公司出品),该系统配备密封式X射线管(Hamamatsu L12161-07),靶材为钨(W),小焦点模式下焦点尺寸为5 μm。我们采用搭载Gadox闪烁体的电荷耦合器件(Charge-Coupled Device, CCD)探测器,其像素尺寸为9×9 μm²,并通过2×2像素合并模式采集投影图像。为保障单只标本获得最优成像质量,我们对多项成像参数进行了适配调整。数据处理阶段,借助仪器配套软件对采集得到的原始数据完成重建。 本次实验的核心成像参数如下: - 管电压(kV):80 - 几何放大倍数:4 - 体素尺寸(μm):4.47 - 采集角度总数:1568 - 单角度累积曝光时间(s):4 - 总扫描时长(误差±10min,单位:h):2.6 - 单角度采集时长:2×2s - 样本旋转圈数:2 - 系统开销占比(%):49.2 - 探测器像素尺寸(μm):18 - 源物距(mm):30.5 - 源检距(mm):122.7
