Hi Jun, The documentation and help pages of these tools are indeed lacking detail. Especially the Fast Marching 3D tool is rather technical in its UI. It's always hard to provide the rights tips for specific segmentations without access to the actual data.
Something that's always worth to look into is our interpolation tools. The 2D interpolation usually results in very accurate segmentations with only a little effort in every n-th slice (either manually or with tools like the 2D region grower), especially when you scroll through an axis that does not has high-frequency changes of the structure of interest. Even though it require a little more work in the beginning, you end up with a segmentation that does not need corrections in contrary to many automatic approaches, which tend to be followed by a long manual refinement process. The interpolation is even more powerful when you use crosshair rotation to optimize the main segmentation axis (render window menu) and texture interpolation (context menu of the image in the data manager). This is also an important feature for the 3d interpolation which is able to segment organs like the liver, kidney, spleen and so on with only around 3-6 arbitrarily oriented slices. The idea is as follows: You segment for example an axial and a sagittal slice of the structure you're interested in and you already get a preview of the final 3d-interpolated segmentation. You can now add more slices and the preview will adapt to the new input. Look for the biggest deviations of the preview compared to the structure of interest and segment another slice. Remember the crosshair rotation capabilities of MITK for this.

For example, how can we get the following segmentation results by the two segmentation tools? [cid:image001.png@01D57DC2.4BE31B80] Looking forward to your reply. Best, Jun
