We present a semi-automatic segmentation algorithm to
create 3D heart models of children with complex
congenital heart disease from 3D magnetic resonance
images, which have promise for planning interventions.
After 10-15 short-axis slices are segmented manually (in
less than one hour of interaction time), a patch-based
algorithm segments the remaining slices automatically.
3D surface models are then generated from the segmented
blood pool and epicardium. The semi-automatic algorithm
was evaluated using images acquired from 4 patients.
Compared to manual segmentation, the proposed algorithm
had surface-to-surface distance errors of 0.51 +/- 0.90
mm (blood pool) and 0.60 +/- 0.99 mm (epicardium).
