Data related to the Publication "<strong>Effect of surface-partial-volume correction and adaptive threshold on segmentation of uroliths in computed tomography"</strong> <br> 101 Uroliths were ex-vivo (volume and diameter) and CT imaging was performed. Data consists of - measured ground truth volume - measured ground truth diameter - CT imaging of all stones - stone composition (when available) <br> <br> Data ist provided as a csv table, and as MATLAB .mat file. <br> <strong>CSV Table Data</strong> Table containing a row for each of the 101 uroliths with colums: ID, Volume, Diameter and Stone Type. <br> <strong>Matlab Data</strong> Matlab structure array of the 101 uroliths with the following fields: <br> gt_diam: diameter (ground truth) gt_vol: volume (ground truth) <em><strong> </strong></em> imgdata 3D data from CT imaging voxsiz voxel size in mm (x y z) voxvol_mL size per voxel in milliliter <br> Some uroliths have cavities, these are filled with NaN values in imgdata <br>与学术论文**《表面部分容积校正与自适应阈值对计算机断层扫描（Computed Tomography, CT）中尿路结石（uroliths）分割的影响》**相关的数据集。 共收集101枚离体尿路结石，测量其体积与直径，并对所有结石实施计算机断层扫描成像。该数据集包含以下内容：实测基准真值体积、实测基准真值直径、所有结石的CT影像，以及结石成分（若可获取）。 数据集以CSV表格与MATLAB .mat格式文件两种形式提供。 **CSV表格数据**：表格每一行对应1枚尿路结石，总计101行，包含以下列：ID、体积、直径与结石类型。 **MATLAB数据**：包含101枚尿路结石的MATLAB结构数组，各字段如下： gt_diam：基准真值（Ground Truth, GT）直径； gt_vol：基准真值（Ground Truth, GT）体积； imgdata：CT成像的三维影像数据； voxsiz：以毫米为单位的体素尺寸（x、y、z轴方向）； voxvol_mL：单个体素的体积，单位为毫升。 部分尿路结石内部存在空腔，此类结石的imgdata字段中对应位置以NaN（非数字）值填充。
