Exporting a Volume

You can use the Volume export function in the Export pane to export a 3D volume for use in third-party DICOM software.

Warning!

An exported 3D volume may be subsampled, which may lead to diagnosis errors. Use subsampled data at your own risk.

Note:

Only axial slices are exported. Other details such as implants and annotations are not exported.
If you use increased slice thickness or a smaller axial matrix size, the exported volume will use up less storage space than the original volume.
You can use the Volume export:
If the third party software does not support JPEG lossless compressed images.
If you need to export your volume with a DICOMDIR.
To anonymize a volume.

To export a 3D volume, follow these steps:

In the toolbar (MPR, Curve and Bilateral tabs), click .

The Volume export appears.

Configure the export settings as required.

1: Select file and directory

Click the Browse button and select the output directory (folder) in which you want the 3D volume to be exported.

You can add a text description in the Description field if required. The text is added to the DICOM tag “Series description”.

2: Select resolution

Select axial matrix size (pixels): Set the resolution of the axial slices for the exported 3D volume.

Select slice thickness: Use the drop-down list to select one of the following slice thickness options:

Isotropic: If selected, the Volume export automatically calculates slice thickness when you adjust the axial matrix (voxel size remains cubic or uniform).
Anisotropic If selected, you can modify the slice thickness settings to give a volume with non-cubic (nonuniform) voxel dimensions.
Changing slice resolution and/or thickness will decrease image quality. Use these options at your own risk.

Note: Changing slice resolution and/or thickness will decrease image quality. Use these options at your own risk.

3: Select output file format

Select file format: Select an axial slice format that matches the third-party software's requirement:

Click Anonymize to remove all Patient Health Information (PHI) from the exported volume.

Click Create DICOMDir to add a DICOMDir data file to the exported volume.

Select compression: Select compressed or uncompressed DICOM output.

Note: DICOM images are usually exchanged as compressed JPEG images in order to conserve file space and bandwidth. However it is not mandatory to do so. An uncompressed DICOM volume can require up to 350 Mb of disk space.

4. Click the Export button.

The current 3D volume is exported to the folder you selected in section 1.

A window will open allowing you to choose the type of volume selections.

5. Choose the selection and Click OK.

To export a scanned object, follow these steps:

After having opened a scanned object appliance, format STL, in CS Imaging, proceed to the Export toolbox.
