Creating models from dicom files in 3 different crossections

[lassoan (Andras Lasso)]

I’ve converted the image arrays in each crosssection in 3 dicom files - 1 sag, 1 cor, 1 ax. Is it possible to open these 3 dicom files in Slicer at once and let slicer interpolate their relative position to one another and construct a model?

Yes, they should be all loaded correctly and appear in the same physical position.

When I tried to open the 3 dicom files at once in Slicer, Slicer could not identify them as 1 single patient (even though I let them have the same patient name). Is there a way to open them as 1 single patient?

Most likely UIDs were not correctly replaced during anonymization. This should not be an issue.

You can load all 3 DICOM files at once, you can switch between them any time and can show a blended display of any two at the same time in any of the slice viewers. You can also use any of them in creating one 3D segmentation. Having 3 sparse (highly anisotropic resolution) volumes is nearly not as good as one isotropic volume - see this topic for details: Combining volumes - what am I missing? - #2 by lassoan

@BlueLan

browsing through past discussions about similar topics. A person has recommended NiftyMic. However, the software seems to only accept .nii files (seems to be file format specifically for neuroimaging ???).

You can save the volume in nifti format using Save data window (select Nifti in File Format column). We don’t have experience with NiftyMic but it seems that you will! Let us know if you find it useful. People quite often struggle with getting a decent 3D volumes from these kind of sparse acquisitions.
