Interactive 3D medical data cutting using closed curve with arbitrary shape
We mix octree and quad-tree to make cutting operation in real-time. 2D mask image and coordinate transformation make users cut 3D volume data in 2D space. The cutting method could improve the accuracy of image segmentation algorithms. The cardiac images segmented results can be used to evaluate cardiac function quantitatively and be more conducive for diagnosis and treatment of cardiac disease.
