OCT raw scans - LR

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轴采样步长分别为40 μm、40 μm、2.18 μm，高分辨率（High Resolution，HR）图像的x、y、z轴采样步长分别为11.1 μm、11.1 μm、2.18 μm。所有扫描图像在为期15天的实验中每3天采集一次。 低分辨率（LR）扫描图像尺寸为250×250×1024像素，存储于名为large的文件夹中；高分辨率（HR）扫描图像尺寸为900×900×1024像素，分别存储于B1（对应FFM）与B5（对应SFM）文件夹中。两类扫描图像均覆盖10 mm×10 mm×2.2 mm的总成像体积。 本次实验共采集66×3帧LR扫描图像，以平铺拼接模式覆盖0.4 m×0.025 m的区域；同时在同一感兴趣区域的极端位置采集了3×3帧HR扫描图像。 每幅.raw格式的扫描图像均配有对应的.json格式元数据文件，命名规则与扫描图像一致。所有文件以采集日期和时间命名，文件名的最后一段用于标识拼接块。各采集日期对应的生物膜形成天数与重复实验编号信息，均记录于OCTScans_metadata.xls文件中。
