Trying to allow different segmentations to be adjusted separately in reader study case

Trying to allow different segmentations to be adjusted separately in reader study case  

  By: Gino on June 27, 2022, 8:37 a.m.

I am trying to set up a reader study to assess segmentations of the heart in 3D CT images. The different segments are marked with different integers in the mask (0: background, 1: LV-cavity, 2: LV myocardium, 3: etc.). When I set up a viewer configuration it displays as desired in the Cirrus viewer:

Now as a reader in a reader study, I would like to be able to adjust those annotations, one segment at a time, and such that the semantics of the mask are preserved. Also, I would preferably not allow overlapping segments. (So for example, if you adjust one segment, and in doing so overlap with another segment, you should override the intersection with the other.)

I know that I have to match the interface of the masks that I upload, with the interface of the annotation task that I create. Is there an interface available that suits my needs, could I request one, or is there some other solution?

Correction of multi-class segmentation is currently not supported in CIRRUS, we are planning to add it in the next release (July 2022). Please keep an eye out on the development blog.

That's soon, thank you. Where can I find the development blog?

This has now been implemented.
