DICOM SEG - 3D segmentations with only one slice cannot be reloaded as DICOM SEG
Open, NormalPublic


How to reproduce:

  1. Take a 3D image
  2. Generate a segmentation that is only on one slice of the image (if it spanns multiple slices, everything works fine)
  3. Store as DICOM SEG
  4. Load the DICOM SEG -> Error/exception.

Reason: DCMQI deduces an invalid origin of the segmentation image and throws an exception. Why? If it is a bug in DCMQI or a usage proplem on our side, is not clear yet?

Did not have the time to investigate further but wanted to report as known issue.

The reason is still unkown. But if you store the segs without skipping the empty slices, then mitk is able to load also segs with one slice.

As we have with T27416 a mitigation strategy for the next reales cycle, I retag it as MITK general. It should be checked somewhen, but given the current needs/information, I don't think it is necessary for the next cycle.
