[The manufacture of pelvic mirror physical model using rapid prototyping].
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.


CONCLUSIONS
The manufacture of pelvic mirror physical model using rapid prototyping was feasible, and the models were quite accurate.
