Based on the ultrasonic training system of CT image simulation and location

The present invention is a kind of ultrasonic training system based on CT image simulation and location, accelerates to realize ultrasonoscopy simulation and CT volume data is played up by GPU, improves the real-time of system.Wherein SURFACES MATCHING module is used for mock-up is standard, the human body CT volume data of reading and mock-up data is carried out surface matching, by realizing the elastic registration of curved surface based on the interpolation method of thin plate spline; Ultrasonic simulation probe posture tracking module calculates ultrasonic simulation probe relative to the pose of solid model in real time for the method adopting monumented point to follow the tracks of, and obtains CT image slice at any angle according to position auto―control; Image enhaucament and ultrasonoscopy simulate generation module for adopting multi-scale enhancement method, improve the vascular contrast in CT image, and realize the simulation of ultrasonoscopy based on CT volume data; What merge that display module is used for completing CT volume data based on the acceleration of CUDA plays up display, and according to the position auto―control obtained, ultrasonic simulation image and three-dimensional CT image is merged and show.
