Title: ULTRASONIC TRAINING SYSTEM BASED ON CT IMAGE SIMULATION AND POSITIONING
Abstract:
An ultrasonic training system based on CT image simulation and positioning accelerates, by using a CPU, the implementation of ultrasonic image simulation and CT volume data rendering, and improves the system real-time quality. A curved surface matching module is used to perform, by using a physical model as a standard, surface matching between read human body CT volume data and physical model data, and implement elastic transformation of the curved surface with an interpolation method based on thin-plate splines; an ultrasonic simulation probe position tracking module is used to calculate, in real time, a position of an ultrasonic simulation probe relative to the physical model with a mark point tracking method, and acquire a CT image slice at any angle according to a position matrix; an image enhancement and ultrasonic image simulation generation module is used to increase the vessel contrast in the CT image with a multiscale enhancement method, and implement simulation of the ultrasonic image based on the CT volume data; and a fusion display module is used to accelerate the implementation of rendering display of the CT volume data based on a CUDA, and fuse and display the ultrasonic simulation image and the three-dimensional CT image according to the acquired position matrix.
