Thank you Stefan for your kind answer.As far as I know it is a raw DICOM file
extracted from US machine Logic E10s (GE Healthcare).
The file is totally anonymized and I will send you a link to download it.

I see, I will extend the ticket to not only handle unsupported pixel types
more gracefully but to maybe also still show statistics that do not depend on
the pixel type like volume and number of pixels of labels. I am afraid none of
this will resolve your issue in the short term since code changes are required.
The empty pixel type is interesting, can you tell us more about the image or in
case it is anonymized give us a sample so we can look up what is going on?
Best,
Stefan

Betreff: Re: AW: [Extern] - [mitk-users] Retrieve segmented surfaces
Hi again Stefan, and thank you again for your help.
I want to measure the surface of a label indeed. And more precisely, calculate
metrics (like DSC, IoU, precision and recall) of 2 labels in a single slice
(for now; we consider expanding to 3d meassurements later).
I already used the method you recommended with Horos: I measured by hand the 2
surfaces and their overlap by hand and I was able to calculate everything I
wanted. So it is possible but time consuming, and also less precise than
automated calculations.
This is why I'd like to use a software with segmentation capabilities for that
purpose.
Thanks
Bernard

Betreff: AW: [Extern] - [mitk-users] Retrieve segmented surfaces
Hi again,
by "surface", do you mean a segmentation label, resp. masked pixels and only in
a single slice? Or all the pixels of a segmentation label (volume)? Or, surface
in the sense of MITK, which would be a 3-d polygon mesh?
The volume of segmentation labels is shown in the statistics plugin, but I
already read that you have trouble with unsupported pixel types, right? If you
are really just interested in the 2-d area of something in an image, and you
just created segmentations for this purpose, an alternative would be the
Measurement plugin, where you can draw a (smoothed) polygon for example to see
the circumference and area in mm².
Best,
Stefan

Betreff: [Extern] - [mitk-users] Retrieve segmented surfaces
Hello,
I'd like to know please how to retrieve the area of segmented surfaces,
including intersection and union surfaces calculated in Boolean operations.
I've been searching for this without succes and I'm new ti MITK Workbench.
Thanks,
Bernard
