Establishment And Application Of 3-D Visualization Model Of Four Limbs' Bone And Joints

Objective: To establish a three-dimensional visualization model of big joints of the four limbs with data based on CT. It could be used in clinic as diagnosis and operation simulation.Methods: Original data of 10 normal volunteers'joints by CT scanning was transferred into the system. Every step was showed with figures. The clear 3D reconstruction were established, and some factors concerned to reconstruction were discussed.Results: Frame and its surface of big joints could be observed clearly in reconstructed 3-D Model. Furthermore, the 3-D Model could be seen from any sight angle and sectioned in any direction and place. Doctors could observe the characters of joints for more details.Conclusion: The most clear and precise model through available conditions were constructed, This model could be used in clinic for diagnosis and operation simulation.1 DFOV that containing interested area should be smaller.2 Slice thickness should be appropriate.3 Threshold segmentation should be proper according to different persons.
