Hello, I have brain RT structs exported from the software “MIM” which when I import into Slicer via SlicerRT have corrupted closed surfaces. [image] As you can see the slice fill has patches missing and points are connected that shouldn’t be. An MRI is the background volume but I’ve made it blac…

It may be just a rendering artifact. Could you please check if the appearance is fixed if you create “Closed surface” representation from n Segmentations module?

When the RT struct is loaded a closed surface representation is automatically created. So per your suggestion I removed the closed surface rep: [image] then created it again by clicking create [image] exact same result [image] I’ve uploaded the RT struct here 0298slicerForum.zip …

This structure set has lots of errors. There slightly non-parallel contours and slightly inconsistent distance between contour planes. There also seem to be a number of left-to-right direction cuts in the contours (see orange arrows; maybe they are keyholes, but then there should be holes in the cro…

MIM has a menu option for “Save surface segmentation” that I used and it created a “SEG” series file [image] However now when I try to load it into Slicer along with the associated volume I see this error window [image] I click OK and see this [image] MIM also has a tool to clean each axial s…

Slicer supports loading of DICOM Segmentation IOD (via QuantitativeReporting extension). However, DICOM Surface Segmentation IOD is not yet supported. It should not be hard to add support for it (you could write an importer Python script), but surface segmentation IOD is rarely used in medical imag…

Here’s a thread on options for surface segmentations: [image] Load DICOM Surface Segmentation Objects Feature requests Slicer version: 4.6.2 Hi, I just wondered, if there is any possibility to load DICOM Surface Segmentation Objects, as described in the DICOM Supplement…

The script to view SEG surface is here , it works. S. options at the beginning to save as VTK or STL to load into Slicer, the script itself only shows the SEG mesh.
