Real-time ultrasonic image simulating method based on CT volume data

An ultrasonic image needs a doctor to have abundant ultrasonic image recognizing experiences when being used for recognizing and judging human tissue posterior ischic optico-neuropthy, and real-time ultrasonic image simulation provides a convenient tool for ultrasonic training. An ultrasonic image simulating method is used for simulating the ultrasonic image in real time on the basis of CT volume data, carrying out inter-conversion on coordinate positions of pixel points of an ultrasonic sector image and a CT rectangular image by adopting a thin plate spline interpolation function, obtaining a reflectivity of a tissue organ interface according to a Lambertian reflection model by using nonlinear compression conversion through calculating a difference proportion of CT values between the two pixel points of a single Ray by combining the characteristic of a tissue organ edge detection operator and the characteristic of CT image and ultrasonic image noise, and realizing simulation of an ultrasonic probe multi-unit transducer through a Hanning Window function. The ultrasonic image simulation has the advantages of high trueness and strong instantaneity.
