ct-uroliths-freiburg

Data related to the Publication "Effect of surface-partial-volume correction and adaptive threshold on segmentation of uroliths in computed tomography"

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)

Data ist provided as a csv table, and as MATLAB .mat file.

CSV Table Data

Table containing a row for each of the 101 uroliths with colums: ID, Volume, Diameter and Stone Type.

Matlab Data

Matlab structure array of the 101 uroliths with the following fields:

    gt_diam:      diameter (ground truth)

    gt_vol:          volume (ground truth)

    imgdata       3D data from CT imaging      

    voxsiz          voxel size in mm (x y z)

    voxvol_mL   size per voxel in milliliter

Some uroliths have cavities, these are filled with NaN values in imgdata
