How do we access the labelmaps2D?

[ahlaughland]

Thanks for Cornerstone as it makes the hard simple and the simple attainable!

I'm having trouble finding the labelmaps2D on the labelmap3D. I searched the Issues and didn't find any infos regarding labelmaps2D.

Here is the scenario I am in:

DCMJS requires that there is a labelmaps2D on the labelmap3D sent to it by cornerstone:
https://github.com/dcmjs-org/dcmjs/blob/9023d1eb9f722a68f117dedc5e9088a70d907f38/examples/createSegmentation/index.html#L155

I'm drawing a segment and getting the labelmapVolume:
const labelmaps3D = cornerstoneCore.cache.getVolume(segmentationId);

But when I pass the labelmaps3D to dcm.js:

const segBlob = dcmjs.adapters.Cornerstone.Segmentation.generateSegmentation(
            images,
            labelmaps3D,
            options
          );

It throws and error that labelmaps2D.length is undefined:

Dcm.js:

This is because there is/are no labelmaps2D on the labelmap:

How would I acquire the labelmaps2D required by dcm.js?

Hi, cornerstone3D does not have labelmap2D like cornerstone legacy had. Do you want to load a DICOM SEG? I have a big PR coming up to OHIF very soon that adds the support with OHIF v3 and cornerstone3D

[ahlaughland]

Hi Sedghi. Yes we would like to load (and save) the DICOM SEG. Can you pass along a link to your PR or what branch you are merging it into?

Thanks again!

[sedghi]

Yes, I will post it here for you

[ahlaughland]

Hi Sedghi. I see you have created a PR for SEGs: OHIF/Viewers#3015

This is some amazing work and I am excited to review it an learn how the code works.

I will close this issue and track changes from the PR.

Thanks again!
