The invention provides an ultrasonic training system based on CT (Computed Tomography) image simulation and positioning. Ultrasound image simulation and CT volumetric data rendering are accelerated to be achieved through a GPU (Graphics Processing Unit) and the real-time performance of the system is improved. A curved surface matching module is used for performing surface matching on read human body CT volumetric data and physical model data with a physical model as the standard and achieving elastic transformation of a curved surface based on an interpolation method of thin plate splines; an ultrasonic simulation probe position tracking module is used for performing real-time calculation on ultrasonic simulation probe positions relative to the physical model by a marking point tracking method and obtaining arbitrary angle CT slice images according to a position matrix; an image enhancement and ultrasonic image simulation generation module is used for improving the vessel contrast ratio in CT images by a multi-scale enhancement method and achieving the ultrasound image simulation based on the CT volumetric data; and an integration display module is used for accelerating to achieve rendering display of the CT volumetric data based on CUDA (Compute Unified Device Architecture) and integrating and displaying ultrasound simulation images and three-dimensional CT images according to the obtained position matrix.
