Custom Size Segment

[manjula (Manjula Herath)]

1. Can some one please help me with in creating a custom Box shape area of segmentation like the Sphere in the “Manipulating objects in the slice viewer” ?

2. Or is there a way to define the ROI and then create a segment out of the region within the ROI box ?
   I need to create a segment with define length and width and height.

3. Is it possible to cut out multiple segments at once ?

The same example works for box shape, too. You can use vtkCubeSource instead of vtkSphereSource.

You can create a box using vtkCubeSource and create a model from that. This is done in SlicerIGT extension’s “Create models” module.

Yes. For this, set masking settings to “overwrite all other segments” and then create a new segment and fill that. If you fill a segment that will erase that region from all other segments.
