Production phases of 3D modeling for printed prototypes and holograms. (A) Digital raw data acquired from imaging sources (CT angiography, MRI) undergo segmentation to create a 3D virtual model. After preprocessing refinement, the stereolithography file is 3D-printed. Models receive postprocessing treatment. (B) 3D virtual model as a hologram can also be imported into virtual reality, where it can be fully rotated and entered.
