Module Description

This is the DICOM / DICOM-RT import module. It allows you to select a directory containing DICOM-RT structure sets and/or dose, which it will convert into 3D Slicer labelmap and/or scalar image. This module also loads the DICOM CT image without requiring the need to use the Slicer volume import wizard.

Note: In a Slicer, a labelmap voxel can only belong to one structure. However, DICOM-RT allows a region to belong to any number of strucutres. Therefore, importing DICOM-RT structure sets as Slicer labelmaps will usually result in a loss of data. This module uses a "last structure wins" strategy for assigning labels to overlapping volumes.

Note: Because DICOM-RT structures are specified as polylines, there is a small loss of fidelity when they are converted into rasterized volumes.

Panels and their use

Input/Output panel: Input DICOM directory: Here you choose any file in the directory which contains the DICOM-RT data. Reference Volume (to set size): This is an optional field. But if your dicom directory does not contain a CT, it is required. Here you choose any loaded volume. The import module will create a labelmap at the same resolution and pixel spacing as the reference volume that you choose here. Output Image: Here you choose where to put the output CT image. Unless you want to replace an existing volume, you should choose "Create New Volume". Output Labelmap: Here you choose where to put the output DICOM-RT structure set labelmap. Unless you want to replace an existing volume, you should choose "Create New Volume". Output Dose Image: Here you choose where to put the output DICOM-RT dose image. Unless you want to replace an existing volume, you should choose "Create New Volume".
