Presentation Transcript

  1. Image Overlay The Surgical Navigational Systems of Tomorrow Presenter: Jeff Hsin

  2. In what types of surgery are they used for? • Neurosurgery • Orthopedics • Microsurgery • Obstetrics • Plastic Surgery • Numerous others…

  3. Guidance with 3D images • A great deal of research has been invested in the possibility of using 3-D images of a particular surgical area in hopes to provide the surgeon with more surgical guidance.

  4. Format of 3-D image: • View pre-operational 3-D images in the form of two-dimensional sectional images displayed away from the surgical area

  5. Present Day Techniques • View the computer display showing the image

  6. Present Day Techniques • View the computer display showing the image • reconstruct and formulate the 3-D image in his head

  7. Present Day Techniques • View the computer display showing the image • reconstruct and formulate the 3-D image in his head • relate the 3-D image, now stored in his head, with the actual patient’s body when conducting the operation

  8. Why this needs to change. • The quality of reconstruction of the image in the surgeon’s mind is dependent upon his surgical experience as well as his anatomical knowledge.

  9. Why Else Does This Need to Change? • Disruptive in the flow of surgery • Leaves room for considerable margins of error

  10. IS THERE A SOLUTION???

  11. IMAGE OVERLAY SYSTEM

  12. What Is It? • A display technique that will superimpose computer-generated images over the surgeon’s direct view of the patient’s surgical area

  13. Who/What are the team-players of 3D Image Overlay?

  14. Computer Graphics Work Station Indiglo-II R10K, made by Silicon Graphics, Inc

  15. Semi-transparent Display

  16. Position Tracking System OptoTrak 3020, By Northern Digital

  17. Registration and Transformation Software

  18. Present Focus of Image Overlay • Intra-operative guidance • Surgical education

  19. Intra-operative guidance • placement of the acetabular and femoral prosthetic implant components during total hip replacement surgery

  20. Intra-operative guidance • placement of the acetabular and femoral prosthetic implant components during total hip replacement surgery • proper placement of screws or intramedullary rods in bone fragments

  21. Intra-operative guidance • Neurosurgical procedures.

  22. Surgical Education

  23. Obstacles to Overcome • Accuracy –detrimental without it.

  24. Obstacles to Overcome • Accuracy –detrimental without it. • Spontaneous changes that occur in biological system. E.g. deformation of skin

  25. Obstacles to Overcome • Accuracy –detrimental without it. • Spontaneous changes that occur in biological system. e.g. deformation of skin • Tracking of the eye

  26. Future of Surgical Systems
