@Eserval and @rbumm, both thoracic surgeons, have been in a video call recently to address the above question.
@Eserval demonstrated his excellent segmentation recipe (100% 3D Slicer) which consists of:
- Lung mask and airway segmentation with Lung CT Segmenter
- Creating a vessel mask
- Creation of empty a PV and PA segment
- Manual placement of seeds in the pulmonary vein and pulmonary artery (complicated stuff)
- Grow from seeds vessel segmentation “inside vessel mask”
- Creation of upper, middle and lower lobe segments (left) and upper and lower lobe (right)
- Slice painting inside right or left lung mask in the lobe segments
- Fill between slices to complete the lobes
- Duplicate the lobes into lung segments
- Use the “Scissor” function to isolate each individual lung segment
- Use “Level tracing” to segment the tumor
The procedure usually takes @Eserval about 1-2 hours. @Eserval if possible please add some cooking stage images and a final result - or a link to a youtube video …
@Eserval and @rbumm agreed on closer cooperation, moving parts of this recipe into the lung CT segmenter, and establishing this thread to collect additional ideas from the community. The final goal will be a semiautomatic planning tool for lung surgery, maybe an additional module in the Chest Imaging Platform.
