The purpose of this study was to evaluate the spatial relationship of facial bone more
accurately.
For this study, the three-dimensional images of dry skull were reconstructed using
computer image analysis system and three-dimensional reconstructive program involved
CT.
The obtained results were as follows:
1. Three-dimensional reconstructive CT results in images that have better resolution
and more contrast.
2. It showed good marginal images of anatomical structure on both three-dimensional
CT and computer image analysis system, but the roof of orbit the lacrimal bone and the
squamous portion of temporal bone were hardly detectable.
3. The partial loss of image data were observed during the regeneration of saved
image dada on three-dimensional CT.
4. It saved the more time for reconstruction of three-dimensional images using
computer image analysis system.
But the capacity of hardware was limited for inputting of image data and
three-dimensional reconstructive process.
5. We could observe the spatial relationship between the region of interest and the
surrounding structures by three-dimensional reconstructive images without invasive
method.
