How can I get lung lobe segmentation (into RUL, RML, RLL, LUL and LLL) given a CT volume ? Which is the best method in slicer ? Please let me know.

I want something like this:

I have tried interactive lobe segmentation but it didn’t work.

A large number of AI segmentation models have been developed over the past few years, but [TotalSegmentator](https://github.com/wasserth/TotalSegmentator) stands out in several aspects: it can segment many structures: 104 anatomical structures (all abdominal organs, bones, larger vessels, muscles) it is very robust: it can segment any whole-body, abdominal, chest CT images, regardless of image…

You can use the Lung CT Segmenter, part of Lung CT Analyzer extension, where the TotalSegmentator AI call is implemented for the lobes.

Great answers already.

You could also use the whole-body CT segmentation model available for MONAI Label: [model-zoo/models/wholeBody\_ct\_segmentation at dev · Project-MONAI/model-zoo · GitHub](https://github.com/Project-MONAI/model-zoo/tree/dev/models/wholeBody_ct_segmentation)

Here are more instructions for using the MONAI Bundle: [MONAILabel/sample-apps/monaibundle at main · Project-MONAI/MONAILabel · GitHub](https://github.com/Project-MONAI/MONAILabel/tree/main/sample-apps/monaibundle#how-to-use-the-app)

If needed, you could fine-tune the model to your dataset.

Hope this helps,
