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

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…

Is there any chance to use “total segmentator” with cone beam CT acquired with angiography systems in the body (liver)? Thanks

Yes, it works on CBCT images as well. However, if the image quality is very bad (which is not uncommon, especially for low-dose acquisitions) then the accuracy will suffer.

Hi, I am trying to make it run and when I look in pytorch utils it said torch version 1.8.1 However, when i run the totalsegmentator it says that it needs to install a higher version of torch (1.12.1) and restart. And then it restarts but nothing happens. Does anyone have any idea what I am doing…

You have some old pytorch 1.x version in your pip cache that gets installed by default. You can go to Pytorch Utils module, uninstall this old version, restart Slicer, go to Pytorch Utils module again, and before you click to install Pytorch, write >=2 in the version requirement textbox. These uni…

Hi @lassoan I have a quick question. I am interested in conducting an experimental campaign on the functionality of TotalSegmentator. For this purpose, I want to modify some parameters and compare the results obtained. I have tried to make modifications from within the program, but regarding segmen…
