Abstract: Example of a high resolution segmentation. The segmentation is smooth in all directions and does not suffer from step artifactsImage Added

We created 66 high resolution segmentations for randomly chosen T2-weighted volumes of




high resolution segmentations were


obtained by considering the three scan directions: for each scan direction (axial, sagittal, coronal), the gland was manually delineated by a medical student,


followed by a review and corrections of an expert urologist. These three anisotropic segmentations were fused to one isotropic segmentation by means of shape-based


interpolation in the following manner: (1) The signed distance transformation of the three segmentations is computed. (2) The anisotropic distance volumes are transformed into an isotropic high-resolution representation with linear interpolation. (3) By averaging the distances, smoothing and thresholding them at zero, we obtained the fused segmentation. The resulting segmentations were manually verified and corrected further by the expert urologist if necessary. Serving as ground truth for training CNNs, these segmentations have the potential to improve the segmentation accuracy of automated algorithms. By considering not only the axial scans but also sagittal and coronal scan directions, we aimed to have higher fidelity of the segmentations especially at the apex and base regions of the prostate.

For a research project about automatic high resolution prostate segmentation, our medical partners created manually 66 ground truth segmentations of the following TCIA collection:

The segmentations were created by considering the axial, coronal and sagittal T2 weighted scans and have isotropic resolution.

The segmentations to standard DICOM representation were created with dcmqi .
