THE 3D RECONSTRUCTION OF TEMPORAL BONE BY MULTI-SLICE HELICAL CT AND COMPARED WITH ANATOMAL MEASUREMENT / 解放军医学杂志

ABSTRACT

In order to verify the dependability of 3D data, twenty-four temporal bones of adult head specimen fixed with formaldehyde were scanned by multi-slice helical CT. The technique of shade surface display and volume rendering were used in reconstruction. The 3D data of the surface structure of temporal bone were compared with anatomical specimens. The result showed that the new type CT has more rapid speed in 3D reconstruction and clearer imaging. The technique of shade surface display and volume rendering can give very clear structure of temporal bone. The 3D data makes no difference with anatomical measurement (no statistic difference). It is suggested that the 3d data can instruct the clinic directly.
