Packing Density
Estimate sac volume from a matched 3D model and track packing density as you add coils.
- Start from a template that matches the aneurysm's shape and enter its dimensions.
- Sac volume comes from the 3D model, not a sphere or ellipsoid formula.
- Add coils from the catalogue to see packing density for the planned set.
