  • Abstract

Through the lunate bone biomechanical analysis can be used for kienböck medical diagnosis and treatment. The pressure sensitive film can reflect intuitively the stress of lunate bone's each point. This paper obtains stress analysis of lunate bone based on PSO (Particle Swarm Optimization) algorithm's image analysis and processing of pressure sensitive film. The paper uses the grayscale function to change a target image into the grayscale image, and uses the PSO algorithm for function optimization to segment image with the original image. Then we obtain remaining achieving gray value, and calculate the pressure. Through the analysis of the experimental data, we obtain the maximum value, minimum value and average value of the pressure. The analysis of processing results showed that the PSO algorithm could segment the image accurately and the remaining larger pixel gray values concentrated in the three fossa of lunate bone. The results verify the accuracy and efficiency of the method.
