Image processing in treatment of digitized virtual Chinese No. 1 female

Objective: To test the feasibility of applying the existing image processing software in treatments of the dataset of the digitized Chinese No. 1 female, such as 3d reconstruction, image segmentation and finite element modeling. Methods: Experimental studies were done on the dataset of the digitized Chinese No. 1 female by using such methods as equal space drawing out, format switch, image segmentation, 3d reconstruction, 3d display and finite element modeling. Result: Several editions of dataset were edited; image segmentation was realized; coronal and sagittal images were reconstructed; the static display was animated; real time 3d display was realized; the regional finite element modeling was set up based on CT images. Conclusion: The different compressed or converted editions of the dataset of the digitized virtual Chinese No. 1 female can meet the given requirements of morphological 3d reconstruction, image segmentation, and real time 3d display, and the skeleton models which are reconstructed on the basis of CT, MRI and sectional images permit the research on the construction of finite element modeling.
