This extension segments lung tissues on basis of density. Voxel-per-voxel segmentation is provided alongside with an averaged version.
The implemented workflow is described in: Zaffino, Paolo, et al. "An Open-Source COVID-19 CT Dataset with Automatic Lung Tissue Classification for Radiomics." Bioengineering 8.2 (2021): 26. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7919807/
The license used is APACHE 2.0.
This module, given a chest CT, segment lung tissue by fitting the intensities with a Gaussian Mixture Model already created. It can be used for pneumonia (COVID-19 too).
Tutorial
- Load chest CT (COVID-19 CTs can be download from https://www.imagenglab.com/newsite/covid-19/ )
- Select Chest CT GMM Segmentation module (in the segmentation menu)
- Select/create a segmentation for the result
- Select/create a segmentation for the averaged result
- Click Apply button
