Mechanical scanning realtime three-dimension ultrasonic imaging system and method

Abstract

The present invention relates to a real-time three-dimensional ultrasonic imaging system based on mechanical scanning. It includes the following several portions: PC machine with USB interface and serial interface, two-dimensional ultrasonic scanner with digital interface, stepping motor and its control and drive portion, in which the USB interface of PC machine is connected with digital interface of said ultrasonic scanner, the serial interface of PC machine is connected with the communication port of the control and drive portion, and the output end of drive module in control and drive portion is connected with input end of stepping motor, the rotary shaft of said stepping motor is fixedly connected with ultrasonic probe of said ultrasonic scanner. Said method includes the following steps: setting scanning parameter; calculating relative position relationship of image; probe initial position resetting; space data collection; three-dimensional data reconstruction; and implementing dynamic image formation of space three-dimensional image.

Description

Technical field: [0001] The invention relates to the field of ultrasonic imaging, in particular to a real-time three-dimensional ultrasonic imaging system and method based on mechanical scanning. Background technique: [0002] Three-dimensional ultrasound imaging is another leap forward in the field of medical image diagnosis compared with traditional two-dimensional ultrasound imaging. It overcomes the problem that the three-dimensional information of the imaged object cannot be described in two-dimensional The display and description of spatial form, as well as three-dimensional imaging guidance become possible. [0003] At present, the 3D ultrasound imaging methods at home and abroad mainly include direct 3D imaging and reconstruction-based 3D ultrasound imaging. Due to the high hardware price of the direct 3D imaging method and the small imaging target area, most of the current 3D ultrasound imaging systems at home and abroad Both are reconstruction-based methods.
