Abstract:

BACKGROUND: It uses computer image processing technology and data visualization technology to reconstruct the human organ with selected mathematical model. 
OBJECTIVE: To simulate the three-dimensional model of focus full of the physical properties of actual object on screen using CT based on human organ deformation and simulation and interaction.
METHODS: Image processing technology was used to process the CT of kidney and the date points of kidney contour were extracted. Through the communication between EAI (External Authoring Interface) of VRML and Java-Applet, the simulation of kidney can be achieved deformed under any external force at any position.
RESULTS AND CONCLUSION: Three-dimensional reconstruction of human kidney was realized based on CT image, and deformation simulation was realized using mass-spring model. Using JAVA and VRML, the kidney was simulated, and the deformation condition was displayed after inputting sequence of size and position of applied force. This study only investigated extension and extrusion, but other deformation can be also realized. This approach gives a new idea for realizing the interaction of virtual surgery system about human organ on web.
