DICOM RT Export
Exporting DICOM RT Data
The DICOM radiotherapy (RT) export function converts DICOM data into a DICOM RT-specific format and exports the data to a pre-configured DICOM network storage target for further processing with 3rd-party systems.
The DICOM RT export uses the DICOM merge library as the transfer protocol to 3rd-party systems. DICOM facilitates the general interoperability between different vendors’ systems. DICOM RT export provides the most recent subset of DICOM objects to facilitate the transfer of specific digital image, graphical and non-image data between two or more systems.

DICOM stores a certain number of points in space that are used to reconstruct contours. Due to different algorithms used by different systems the actual representation of the contours may vary with a very high likelihood but only in small scale. Nevertheless, these different interpretations may result in slight deformations of the contours and differences in size of the volume. Therefore, carefully verify the structures after import on a third-party system.
Exporting 3D Objects and Annotation Points
During export, 3D objects and annotation points are converted to the so-called “DICOM RT structure set” format, during which objects are re-sampled according to the related image set or a fused image set contained in the current selection.
There are two possible configurations for the export of 3D objects and annotation points:
Default configuration: All objects are exported in the context of the original image set they were created in. If the original image set is not selected among the data for export, the latest CT image set that is fused to the original image set is chosen as base set for the export. If you selected MR image sets only, the set with the largest volume and smallest voxel size is chosen. If you did not select any fused image sets for export, the export process is aborted.
All objects are created in the latest CT data selected for export. If objects are selected that are not fused to this CT image set, these objects are not exported. To change the default configuration, contact Brainlab support.
