Imaging Advancements

• Technology Advancements have made Cone Beam CT
  Systems Practical
• Lower Radiation (equal to 3 to 5 Pans)
• High Resolution in All Dimensions (100 to 250
  microns)
• Poor Image Quality and Minimal Tissue Detection
• Three Dimensional Photographic Systems Provide
  High Resolution Surface Images

Considerations

• Solid Coordinate System
• An origin
• Set of transformations for desired orientation
• This data can travel with the image in a metafile

4
Initial Interest

• Temporo-mandibular joint surgery
• A look into an anatomical region before surgery
• Surgical Model
• Prosthetic Molds

Anatomical Landmark

• An anatomical landmark is a unique point within
  the anatomy of a patient that can be easily
  identified and used for image registration

Comparisons

• Combine images from multiple sources to create
  more useful tools for medical analysis.
• Compare images from different time periods to
  track growth/deterioration.
