Workflow in Model Production

Schematic workflow

The general process is as follows:

• CT:
  Acquisition of volume CT data (spiral CT; double detector system)
• Transfer to the workstation (via Local Area Network or disk)
• Workstation:
  Quick 3D surface rendering (to get an overview of the anatomical context)
• Workstation:
  Definition of modeling volume by defining contours slice by slice
• Workstation:
  Choosing interpolation parameters (depending on type of model)
• Workstation:
  Conversion to the appropriate file format (depending on type of model)
• Transfer to the modeling system (disk)
• Modeling system:
  Production of model

CT Volume Data Aquisition - Why?

Computerized tomography currently is the only distortion-free method for volume data acquisition.
In the future, MRI (Magnetic Resonance Imaging) might gain importance, but there are still problems, such as the signal-to-noise ratio.
