Hi , I am trying to segment bone from 4D Ct - multivolume sequence. Because of the displacement of bone from frame 1 to2 and thereafter , I cannot do one frame and do a registration. Looks like I have to manuallu segment each bone for each time point. My question is , how can I do that- when I se…

To allow segmenting each time point of the image, you need to create a segmentation sequence: Create a new Segmentation node (e.g., by segmenting image at one timepoint) Go to Sequence browser module Click the green “+” button next to “Create new sequence”. This creates a new sequence that will st…

Thank you very much Prof Lasso @lassoan If I may ask, how would I mask other bones when doing a rigid registration of a single bone. Following are my screenshots [image] Each tiny bone moves about 30-40 degree angle from the starting frame to the end in my volume sequence. I currently crop each …

When bones are so close to each other then the mask would be about the bone itself. Since you can segment these bones without too much difficulty using Grow from seeds effect with the new masking feature , a good approach could be to use “Segment registration” extension to register segments one by o…
