The TotalSegmentator AI model is now available as an extension for 3D Slicer version 5.2 and above (see installation instructions here ). [image] A large number of AI segmentation models have been developed over the past few years, but TotalSegmentator stands out in several aspects: it can segm…

This is extremely beautifull!!! Cant wait to try it out! Im amazed!!! <3

Thank you for replying. I found paraspinal muscles segmentations. I`ll try for the rest of muscles what you explained for Rotator Cuff.

Hi Lassoan, Very impressive work! Are you able to add option to smooth all the contours generated via fast option? Hoping this can reduce the jaggies? Thanks, LipTeck

Yes, you can apply smoothing in Segment Editor. However, that would not make the segmentation more accurate, so I would not recommend doing it (unless you just want to improve the look of the segmentation). If you want better image quality but you don’t have a GPU then you can get the full quality s…

Hello, I have problems to install totalsegmentator, already I have read the document several times where, and I have made several attempts to install it without results. Can someone explain to me how to install it? a tutorial video?

Please describe what you did, what you expected to happen, and what happened instead. Include screenshots and copy here all messages displayed in the log window of the TotalSegmentator module.

Will this plugin use our local weights to compute(refined or trained by my local dataset), and the weights uploaded to googledrive for users to download

Congratulation for implementing TotalSegmentator to Slicer. I use Slicer to segment bones of the lower extremities and wondered, if you are planning on implementing the v2.0 of TotalSegmentator as well? I would greatly appreciate this work as the segmentation of the lower extremity is enabled in thi…

Yes, it is planned to implement TotalSegmentator v2 as soon as possible.

We have a functional prototype in this pull request of TotalSegmentator v2 in Slicer. We need to tune a few small things before we release it, probably in a week or so. If you don’t want to wait for that then you can get the updated TotalSegmentator.py and .ui files from github and overwrite the fil…
