Filling in empty slices

[junxiant]

Hello,
I am converting a DICOM Seg file, which contains no empty slices (No mask annotations). After I have converted it into nifti format, I got a segmentation mask which works exactly, except the missing slices are not included.

Is there a way to include these empty slices with reference to the original DICOM scan?

Or will i need to

1. Write these SEG into dicom files
2. Match these SEG's referenced_instance_uid to the original scan's SOPInstanceUID, and create empty slices in between?
