Hi
I am new to Slicer and I want to do multi-stages segmentation: 1. segment only lungs from CT images; 2. segment only vessels from the segmented lungs
I am wondering if I can load segmented lung mask (using chest imaging platform) and then only segment inside of the regions of the masks (using VMTK)? I tried VMTK first, but then it segments not only vessels but also a lot of surrounding areas so I was thinking if I do it in multi-stage, it might achieve better results (lung first, then inside of lung, vessels)
Many thanks
