3D printing of prostate model, anatomical fidelity analysis and organ physical behavior prediction using the 3D printed prostate model. a) Procedure for converting patient-specific MRI to G-code for the 3D printing process. b) 3D printing process of the prostate model using the customized polymeric ink. c) Photograph of the 3D printed prostate model. d) An MRI image obtained via scanning a 3D printed prostate model. e) Calibrated distance map via 3D registration for comparison of anatomical fidelity between patient prostate and 3D printed prostate model at the outer surface (left) and urethra surface (right). f) Histogram of the calibrated distances of the surface points for comparison of anatomical fidelity between the patient prostate model and 3D printed prostate model. g) Total deformation results after compression of the FEM model (15% of model height). h) Displacement comparison for feature dots between results from compression of the 3D printed prostate model (with standard deviation error bars) and the FEM simulated model. Inset: Displacement of the feature dots on the 3D printed prostate model after compression with the displacement trajectories. i) Reaction force comparison between results from compression of the 3D printed prostate model and the FEM simulated model.
