Objective:
To study the manufacture of pelvic mirror physical model using rapid prototyping and the accuracy of the models.
Methods:
The pelvic CT images were acquired by spiral CT thin slice scanning, and the slicing data of pelvis were created from these CT images by computer image-processing. Then the pelvic mirror physical model was manufactured using rapid prototyping. The model of a cadaver pelvis and the pelvic model of an experimental dog were manufactured respectively using the method above, and the accuracy of the models were examined.
Results:
The model of the cadaver pelvis manufactured with this method was very similar to the cadaver pelvis. So was the pelvic model of the experimental dog.
Conclusion:
The manufacture of pelvic mirror physical model using rapid prototyping was feasible, and the models were quite accurate.
