I use function of “ theshold ” to get the vessel of liver ,including hepatic vein and portal vein. And then the color of hepatic vein is same with portal vein in same segment. My question is How to get hepatic vein and portal vein in different color ? or how to get hepatic vein or portal vein in different segment ? Any recommendations ?
If you have a good segmentation with both (Seg1), Clone the segmentation (Seg1 and Seg 2 identical). Then use the scissors (or another tool) to remove the portal vein from Seg1. Then Subtract Seg1 from Seg2. Assign different colors to Seg1 and Seg2.
