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>本数据集关联发表论文**《表面部分容积校正及自适应阈值对计算机断层扫描（computed tomography，CT）中尿路结石分割的影响》**。研究人员对101枚尿路结石进行离体样本处理并测定其体积与直径参数，同时完成CT成像。数据集包含以下内容：实测真实体积（ground truth）、实测真实直径（ground truth）、所有结石的CT影像数据、结石成分（若可获取）。 本数据集以CSV表格与MATLAB .mat文件两种格式提供。 **CSV表格数据**：该表格每行对应101枚尿路结石中的一枚，包含ID、体积、直径与结石类型共四列字段。 **MATLAB数据**：包含101枚尿路结石的MATLAB结构数组，各字段如下： - gt_diam：真实直径（ground truth） - gt_vol：真实体积（ground truth） - imgdata：CT成像的三维影像数据 - voxsiz：体素（voxel）尺寸，单位为mm（x、y、z轴方向） - voxvol_mL：单个体素的体积，单位为mL 部分尿路结石存在空腔，其imgdata对应位置以NaN值填充。
