Abstract:
Objective To study the establishment methods of virtual three-dimensional cerebral aneurysm models by using three-dimensional moulding software.Methods The virtual model including the cerebral arteries and the aneurysms were established by using the three-dimensional moulding software of 3D Studio MAX R3 in 20 cases of normal cerebral DSA image and 216 cases of cerebral aneurysms DSA image as the original.Results ①In comparison with DSA image,the virtual cerebral arteries possessed similarity in appearance,and had a benefit for understanding the vascular three-dimensional spatial relation in visual sense.The virtual cerebral arteries could display the virtual guide wire and catheter in semitransparent.The several models of different variant anatomy could be established easily based on the copy files of the virtual cerebral arteries model;②In comparison with DSA image,virtual cerebral aneurysm could display the location of development,direction of growth and feature of appearance correctly.The several aneurysms models of different location,direction of growth and appearance could be established easily based on the copy files of the virtual cerebral aneurysms model.Conclusion The virtual three-dimensional cerebral aneurysm models that were established by the software method can display the three-dimensional spatial relation of the cerebral arterial system and aneurysmal shape distinctly,and would be useful in assisting morphology study and guiding clinical work.
