OCT raw scans - HR

OCT scans at two lateral resolutions (40 um, 40 um, 2.18 um <i>x,y,z</i> respectively, labeled LR) and (11.1 um ,11.1 um and 2.18 um, labeled HR) were taken every 3 days in a 15 days experiment. LR scans have dimension 250 x 250 x 1024 pixels and are contained in folders name large. HR scans are 900 x 900 x 1024 pixels and are contained in folders names B1 (for the FFM) and B5 (for the SFM). Both HR and LR scans covered a total volume of 10 mm x 10 mm x 2.2 mm. 66 x 3 low resolution (LR) scans covered an area of 0.4 m x 0.025 m in a tiled pattern. 3 x 3 high resolution (HR) scans were taken at the extremes of the same area of interest. Each scan (in .raw format) has a relative .json metadata file named accordingly. Files are labeled with the date and time of acquisition, while the last part of the file name identifies the tile. Days of biofilm development and replicate for each acquisition date are reported in the OCTScans_metadata.xls file.<br>

本数据集包含两组光学相干断层扫描（Optical Coherence Tomography, OCT）图像，其横向与轴向分辨率分别为：低分辨率（LR）组的x、y方向分辨率为40 μm，z轴方向分辨率为2.18 μm；高分辨率（HR）组的x、y方向分辨率为11.1 μm，z轴方向分辨率为2.18 μm。本次实验周期为15天，每3天采集一次扫描图像。低分辨率扫描图像的维度为250×250×1024像素，存储于名为large的文件夹中；高分辨率扫描图像的维度为900×900×1024像素，分别存储于对应FFM的B1文件夹与对应SFM的B5文件夹中。高低分辨率扫描图像的总覆盖容积均为10 mm×10 mm×2.2 mm。66组×3次的低分辨率扫描以平铺拼接模式覆盖了0.4 m×0.025 m的区域；3组×3次的高分辨率扫描则采集于同一感兴趣区域的边界位置。每幅.raw格式的扫描图像均附带同名的.json元数据文件，文件以采集日期与时间作为命名标识，文件名末尾部分用于标识对应的拼接块。各采集日期对应的生物膜培养天数与重复实验信息已记录于OCTScans_metadata.xls文件中。
