As a title I’m curious to know how to display 2 or more volume in the same scene, with transparence effect, to show internal anatomic structures thanks

Hi, In python interface: Perhaps by: slicer.modules.models.logic().AddModel(myPolyData) or slicer.modules.models.logic().AddVolume(myPolyData)

Hello. Thank you for reply but I’m a beginner user and I’m able to use only a graphic interface… :frowning:

do you mean a result like this? [23] I’ve done with philips workstation, but i’m interest too to have a similar result with Slicer… I will try

In general, anatomical images are complex enough that display them by simple blending has limited use. You can try it easily in slice views, select one volume as foreground, another one as background, and adjust the foreground visibility slider. What works quite well (but of course somewhat more wo…

I’ve 3 volume in volume rendering: the mail volume (dataset base) volume 1 segmented from main volume using mask volume 2 , similare to volume 1 but not sliglty different In volume rendering I can display correctly each of them but not all together ???!!

Yes, you can show one volume using volume rendering at a time, all the others have to be segmented. By using Segment Editor module, you can often create high-quality Segmentations quite easily. Multiple volume rendering may be added to VTK in the near future and then we’ll enable that in Slicer as …

but we can display multiple model as here? http://www.spl.harvard.edu/publications/bitstream/viewbiglogo/2037/BrainAtlas-Snapshot I need to save segmentation as model?

[image] AndFor: display multiple model as here? Yes, of course. You can adjust display parameters of all segments globally or individually for each segment - in Segmentations module Display section. If you prefer, you can also export all segments to model nodes using Export/Import section.

Good, I’ve downloaded the pre-made model http://www.spl.harvard.edu/publications/item/view/2037 I’ve see that we can use a different opacity for simultaneus 3D models

Note that you can also access these anatomical atlases conveniently in Data Store module (Slicer automatically downloads and caches the selected atlas and other sample data sets).
