how can I get lung vessels? i want to get lung vessels without lung body Thanks !

You need a lung CT with good vessel contrast. In Slicer, you can use the CTACardio demo data set for example. We found that the new “Local Threshold” function in Slicers´s “Segment Editor” works very well for extracting the pulmonary artery (blue) and vein (red). The demo dataset has a limited res…

thank you very much !!! you are the best!

Another way to achieve vessel segmentation is to use the “Grow from Seeds” function in the “Segment Editor”. More manual work, but you get additional airways and lung shadow. I usually define lungs, trachea and bifurcation, pulmonary artery, pulmonary vein and “Other” (paint a circle around the tho…

gracias de nuevo! pero no le eche cuenta a su esposa jajajajaja

Very interesting, could you post a short workflow ?

Muchas gracias! lo voy a mirar y a ver que tal! gracias!

Sure Rudolf-I used version 4.13.0-2020-12-10 for the following workflow: CIP>Lung CT Segmenter Segment Editor>additional segment painted over hilum/cardiac area Trachea replaced using Flood Filling for deeper segmentation PA and PV> Flood Filling Editable Area>Inside All Segments>Allow Overlap …

Hello, I am relatively new to Slicer so can you explain in further detail exactly what you do when you start using the Segment Editor (“Segment Editor>additional segment painted over hilum/cardiac area” ) for the extracting the pulmonary vessells. Many thanks

[LUNG_VESSELS] Hello-that refers to Segment_1 circled in red. I found that by encompassing the entire area of interest, Flood Fill tool gave great results with minimal additional editing in this particular case. I experimented with this workflow omitting this step and found the segmentation diff…

Hello,

CIP Lung Segmenter, Flood Fill and Logical Operators Subtract were the only effects I used for these results. The scan slice thickness is .06 mm and most of the iv contrast was in the pulmonary artery. Hope this helps.
