Basic Segmentation Test

TestProcedureSlice119Start.png
Figure 1. The starting point for the segmentation, slice 119, 1 single red cross (a seed).
TestProcedureRegionGrowingOutline.png
Figure 2. Lower threshold of 71, Upper Threshold of max=325 gives the region growing outline.
TestProcedurePolyToolSeedRightTemporalLobe.png
Figure 3. With thresholding on, adding a seed causes immediate region growing.
TestProcedurePolyToolLines.png
Figure 4. Using Poly Tool to draw round the edge of the region causes the region growing to be blocked.
TestProcedurePolyToolRegionAccepted.png
Figure 5. When changing slice, any thresholded region is accepted.
TestProcedureDrawToolRegionPlusArrow.png
Figure 6. Add seed with Draw Tool, and tidy top of region before moving the seed contained within a single voxel 1cm to the left onto a black background.
TestProcedureCleaned.png
Figure 7. Cleaning removed extraneous contours, and regions without seeds.
TestProcedurePriorNext.png
Figure 8. See Prior and See Next show the outline of the previous and next slice.
TestProcedureDrawToolErase.png
Figure 9. The middle mouse button erases the current contour (orange), thresholding is on, so the region growing tool expands the region, and the green outline is the previous location of the region boundary before we erased the orange edges.
TestProcedureWipeMinus.png
Figure 10. Erasing all slices down (posterior) can be seen in the small helper view.
TestProcedureResult.png
Figure 11. In Dementia Research Centre document, the volume should be 1179.13 (ml) +/- 0.25, and the mean intensity = 87.8 +/- 0.1. Here we are within range.
TestProcedureResult3D.png
Figure 12. The segmented brain, shown here by switching the view to 3D, and then right clicking on the segmentation in Datamanager, and selecting 'Create smoothed polygon model'.
