Data Driven Models
When a project requires models with a high degree of anatomical accuracy, I use actual patient data from MRI, CT, or X-Ray scans to form the foundations of the object. Using software such as 3D Slicer or Osiris, I process the scan data to filter out the structure I am interested in (such as bone, vessels, or nerves). I can then import the data into ZBrush for refinement as the models produced typically have a stair-stepping effect caused by the scan. I may also need to add in missing portions of the model, such as thin bone that doesn't show on scans. When changing the models in any way, I use several textbook and published sources to ensure fidelity.
