OCT Raw scans - LR -Flume II

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. HR scans are 900 x 900 x 1024 pixels, andtheir filename contains 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 each. 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>本数据集包含两种横向分辨率的光学相干断层扫描（Optical Coherence Tomography，OCT）图像：低分辨率（Low Resolution，LR）图像的x、y、z方向分辨率分别为40 μm、40 μm、2.18 μm，高分辨率（High Resolution，HR）图像的x、y、z方向分辨率分别为11.1 μm、11.1 μm、2.18 μm。实验为期15天，每3天采集一次扫描图像。低分辨率扫描图像的尺寸为250×250×1024像素，高分辨率扫描图像的尺寸为900×900×1024像素；两类扫描的文件名分别包含标识B1（对应FFM）与B5（对应SFM）。单幅高低分辨率扫描图像的覆盖体积均为10 mm×10 mm×2.2 mm。66组×3次的低分辨率扫描图像以平铺拼接模式覆盖了0.4 m×0.025 m的区域；3组×3次的高分辨率扫描图像则采集于同一感兴趣区域的边缘位置。每幅以.raw格式存储的扫描图像均配有同名的.json格式元数据文件。所有文件以采集日期与时间命名，文件名末尾部分用于标识对应的拼接块。OCTScans_metadata.xls文件中记录了每次采集对应的生物膜培养天数与重复实验编号。
