So you want your pictures to look good like mine?


Step into my office and let me show you how.


1. Load your amira raw file as well as your image file. Associate the image data to the raw file.

2. Go to the segmentation editor and load up your image (mine's shown in green as material 2)

3. Make 3 new materials and change the color of the first one to blue (this will be -1000 -> -200 HU), another to yellow (-200 -> 0), and another to red (0 -> +200). Click on the colored box next to the name of the material to change the color (drag a color to the "current color" area)



4. Next go to the Threshold tab (on the bottom). Adjust the Display and Masking to -1000 to -200. Before you check "current material only" make sure that you are selected on material 2 (or whatever your lung label material is). Click select.



5. Now go to the yellow material and click the plus button to add the voxels to that material.



6. Now do the same thing with the -200 to 0 HU threshold (be sure you're on the lung label material before selecting), and then add it to the blue material. Then repeat for 0 to 200 HU for the red material. Now you're really cooking with gas.

7. Change from the thresold tab to another tab to get rid of all that extra color in the image. Then change the draw style for the materials to "dotted" (I think this one looks best)



And that's basically it! Save this as a new image file (don't overwrite your label that you used to make this!).
