Four-dimensional imaging technology can directly display the three-dimensional structure of human organs and dynamically observe the three-dimensional structure in real time, while the previous two-dimensional imaging technology can only display a certain section of human organs. In plastic surgery, four-dimensional color Doppler ultrasound can be used for ultrasonic examination of Ogilvy's patients, and can stereoscopically display the fusion degree of Ogilvy's particles with human tissues and the position distribution of Ogilvy's particles in human tissues at all levels. Make the positioning result of Ogilvy's preoperative diagnosis more accurate and clear.
