| − | | + | [[Documentation/4.8/Modules/FastGrowCut|FastGrowCut]] extension has been completely reworked, hugely improved in performance, robustness, and usability, and moved to a built-in effect of Segment editor module named as [https://slicer.readthedocs.io/en/latest/user_guide/module_segmenteditor.html#grow-from-seeds-grow-from-seeds Grow from seeds] effect. |

| − | Step 1.) Add data volume to segment
| |
| − | | |
| − | [[File:LoadMeningioma.png|500px]]
| |
| − | | |
| − | | |
| − | Step 2.) Go to the “Editor” module, select the volume loaded in Step 1 as the “Master Volume” in the “Create and Select Label Maps” drop-down menu
| |
| − | | |
| − | [[File:StartEditorMeningioma.png|500px]]
| |
| − | | |
| − | | |
| − | Step 3.) Select the “CarreraSlice” effect in the “Edit Selected Label Map” drop-down menu
| |
| − | | |
| − | [[File:CarreraSliceEffect.png|50px]]
| |
| − | | |
| − | | |
| − | Step 4.) Set the “Radius” parameter, the "Number of Iterations" and press the “Start Interactive Segmentor” button ( CarreraSlice is now running in the background until the “Stop Interactive Segmentor” button is pressed)
| |

| |
| − | | |
| − | | |
| − | Step 5.) Turn “On” all three slice views in the 3D Plane
| |
| − | | |
| − | [[File:TurnOnSlices3DMeningioma.png|500px]]
| |
| − | | |
| − | Step 6.) Initialize the segmentation using fast GrowCut
| |
| − | * (a) go to PaintEffect to draw seed regions (label 1 for foreground and 2 for background), then press 'G' to run fast GrowCut.
| |
| − | [[File:FGCSeed.png|500px]] [[File:FGCSeg1.png|500px]]
| |
| − | | |
| − | * (b) If not satified, press 'S' to toggle between seed image and segmentation result. Edit on the seed image to reduce over/under segmentaions.
| |
| − | [[File:FGCSeed2.png|500px]]
| |
| − | | |
| − | * (c) Once finished editing on the seed image, press 'G' to run fast GrowCut again.
| |
| − | [[File:FGCSeg2.png|500px]]
| |
| − | | |
| − | The steps 6 (b) and (c) may be repeated a couple of times until satisfied.
| |
| − | | |
| − | Step 7.) Once satisfied with the initialization, press 'M' to start KSlice interactive segmentation. The energy functionals available are:
| |
| − | * (a) press 'F' for local-global Chan-Vese segmentation
| |
| − | * (b) press 'U' for mean curvature smoothing
| |
| − | * (c) press 'E' for Chan-Vese segmentation
