AACIMP 2010 Summer School lecture by Dmitriy Gorlov (Materialise). "Information Technologies" stream. "Innovative Technologies of 3D-Modelling in Medicine" course. More info at http://summerschool.ssa.org.ua

1. Innovative 3d modeling in medicine
Инновационные технологии
3d моделирования в медицине

2. Scope of the presentation…
• About Materialise
• Technical introduction:
- Starting from CT/MRI images, Mimics software can
make an accurate 3D reconstruction of the
anatomical structures and export STL files.
- 3-matic software is capable of designing implants
based on these 3D reconstructions, on STL level
(no reverse engineering necessary)
- The final implants can be produced by Direct Metal
Laser Sintering

8. What is Mimics?
3D Model
• Mimics allows you to:
• import scanned images
• select structures in the images
• These structures can then be
used for different applications…
CT or MRI Scan 2-D Cross Sections Mimics Software
Prof. Dr. De Backer, UZ Antwerp, Dep. Pneumology

9. Mimics provides:
• A link between scanned images and...
• Rapid Prototyping
• CAD
• Finite Element Analysis
• Surgical Procedure Simulation

10. Rapid Prototyping
• Use Mimics for the production
• of Medical Models
• Easy Creation of STL files
• Direct export to RP formats
• Create Supports in Mimics
• Color stereolithography
• Medical Models:
• Communication
• Surgery Preparation
• Proven to be very accurate
and useful
• (cfr. Phidias – European Dr. George A. Brown

26. Surgical procedure Simulation
• Use Mimics to gather measurements for e.g.
statistical analysis

27. Implant placement and surgical
simulation

28. The design of a custom prosthesis
Materialise

29. Classification of cranial prosthesis
1. ‘Simple’ Cranial defect 3. Missing orbit
2. Large cranial defect

30. 1. Design for a simple cranial defect

31. Strategy - Example
• Draw a curve around the defect Curve
• Make sure you draw it far
enough from the border since
we will make a tangential
hole filling
• Use the “Create Cranioplasty
Prosthesis” function

32. Result

33. 2. Design for a large cranial defect

34. Example
Dr. Haex, AZ Maastricht

35. 3. Design for missing orbit

36. Example
•The mirrored skull positioned at
the desired spot
Dr. Taha, CHU Amiens

37. Example: verification in Mimics
