Fig 4. FEM phantoms designed for generating the training data.

Fig 4

(a) FEM phantom comprising lungs and heart in the simulation of human thorax. The radii of lung and heart were varied from 0.3–0.6 and 0.1–0.3. (b) The corresponding lung phantom, which is considered as the training target. (c) The corresponding heart phantom, which is considered as the training target.
