Apply filters on vtkMRMLVolumeNode and then display the filtered volume in Slicer

I want to normalize an image to obtain standardize intensities before doing automatic segmentation.

Applying linear intensity scaling will most likely not affect automatic segmentation results. Even the most basic methods are insensitive to global image brightness/contrast adjustments.

Check out segmentation tutorials and read these posts to have an idea how you can segment semi-automatically or automatically in Slicer:

Automated Spinal Cord Segmentation

Some initialization (albeit very limited) is required by the user (which may impede its effectiveness) You can usually automate seed placement and thus have a completely automatic method. For example you can register a generic “atlas” image and transferring seeds to the patient image. Or you may use simple global thresholding to get candidate regions and keep the most likely candidate (that meets minimum size and shape requirements). You may also use the segmentation that sct provides as seed…

Segmentation method for cerebrspinal fluid space

Hi, I am a new 3D slicer user. I am looking to build a 3D model of the cerebrospinal fluid space from CT images of the human brain. I was wondering if someone could elaborate on how I should go about it. I tried using thresholding in the editor module as they have a predefined scale for CSF space, but that didn’t quite work out. Any help would be great!

Bone segmentation to create 3D-printable STL

Prof. Doc. Andras, Dear Everyone, I was writing back to you . I have fixed the stl export issue. I used segmentaions module>export,models>export. and finally could save it as a stl file. Thank you again Professor for the support. All the best, Hanaa[image] [image]
