High resolution anatomic model fabrication from CT: Visualizing 3-D error

A new CAM rapid prototype technology is being used to produce life-size anatomic models for custom prosthesis design and surgical planning. An 80 slice CT study was used to produce three bone models with stereolithography, each employing variations in solid models derived from segmented CT data. The...

Description
Summary:A new CAM rapid prototype technology is being used to produce life-size anatomic models for custom prosthesis design and surgical planning. An 80 slice CT study was used to produce three bone models with stereolithography, each employing variations in solid models derived from segmented CT data. The error in linear measurements between the CT data and the fabricated model is discussed and a procedure involving a secondary CT scan of the plastic fabricated model and subsequent registration and visualization of error is presented.
