Several papers describe that they have done it but it is very vague. The main problem is to define the anterior and posterior limits of the alveolar bone.
So far the best result I got was with the fill between slice option. Looking for a better and predictable way of segmenting this area to measure the volume which is not very nice in the anterior margin. (Superior and Inferior is not a problem as it can be defined with landmarks.
The images are very helpful but it is still not very clear what the main challenge is. Could you join the segmentation breakout session tomorrow at 2pm EST and bring this as a case to look at?
We agreed on Monday to move the segmentation session to the afternoon because we wanted to have a segmentation storage format discussion and we could not find any other timeslot that worked for everyone. I updated the time in the breakout list, but not in the calendar. This afternoon I fixed this, they are now in sync.
You can use the “Markups to model” module (provided by MarkupsToModel extension) to define the pyramid model by dropping a couple of markup points. You can get the volume of the model in Models module / Information section.
You can improve the accuracy by importing the model into a segmentation and refine the shape in the Segment Editor module.
