Does version 4.5.1 support viewing fused PET/CT images?

Hi, thank you for your work on Weasis.

I’m currently using Weasis v4.5.1 to view PET/CT studies. Both my PET and CT series have the same Frame of Reference UID, belong to the same patient and study, and are correctly loaded into the viewer.

However, I’m unable to find the option to overlay or fuse the PET image on top of the CT.

For reference, the same DICOM data can be viewed as fused PET/CT images in other DICOM viewers (e.g., RadiAnt, Slicer), so I believe the dataset is correctly formatted.

My questions:

Does Weasis 4.5.1 officially support fused PET/CT image display?

If yes, how do I enable or access the fusion/overlay function?

Are there any known limitations or prerequisites beyond Frame of Reference UID matching?

Currently, Weasis does not support displaying fused PET/CT images. This functionality has not been implemented yet.
