ABSTRACT

Objective:

To establish a three-dimensional visualization model of craniofacial hard and soft tissues with data based on CT. It could be used in clinic as diagnosis and operation simulation.

Methods:

Original data of patients' craniofacial hard and soft tissues by CT scanning was transferred into the system. After 2-D and 3-D image preprocessing, advanced Marching Cubes Algorithm (Marching Tetrahedron Algorithm) was used for surface fitting;3-D volume rendering was accomplished by footprint method.

Results:

The whole craniofacial frame and its surface could be observed clearly in reconstructed 3-D Model. Furthermore, the 3-D Model could be seen from any sight angle and sectioned in any direction and place. Doctors could observe the characters of craniofacial deformity for more details.

Conclusion:

The problems of X-ray reflection of metal brackets, control of X-ray dosage and time spending in 3-dimensional visualization model reconstruction were solved. This model could be used in clinic for diagnosis and operation simulation.
