Embodiment Construction
[0050] Combine below Figure 1 to Figure 9 , the present invention is further described:
[0051] The present invention uses a two-dimensional surface array ultrasonic sensor probe composed of a plurality of linear array probes to complete the scanning and imaging of three-dimensional imaging targets, replacing the current traditional one-dimensional linear ultrasonic probe for two-dimensional imaging, and obtains The received data is the channel data received by the two-dimensional surface array ultrasonic sensor probe. They contain the spatial three-dimensional information of the imaging target. By transmitting the wide-beam ultrasonic signal to the imaging target multiple times, and adjusting the receiving data statically or dynamically The distance between the detectors, the coherent data and closed-loop coherent data between different receivers obtained by the data obtained by these receivers according to the method described in the present invention, and the three-dimens...

The invention relates to a three-dimensional ultrasonic interference imaging method adopting a plurality of linear array acoustic sensors. The method comprises the following steps: step 1, arranging a two-dimensional transmitter composed of a plurality of one-dimensional linear array ultrasonic sensors and a receiving ultrasonic sensor; 2, a certain one-dimensional linear array ultrasonic sensor transmitter transmits multiple groups of wide-beam sound waves in different directions to an imaging target, and meanwhile, reflected signal channel data received by a two-dimensional receiver is subjected to AD conversion; step 3, the processor performs Fourier transformation on the converted channel data to obtain each frequency component of the data and form coherent data and closed-loop coherent data; step 4, the least square solution of an objective function J (I) is solved by optimization to obtain a reconstructed image I of scattering intensity; and step 5, scanning, displaying and converting the reconstructed image I to obtain an image pixel value with a length-width ratio, and finally sending the image pixel value to a display device for displaying.
Description
technical field [0001] The invention relates to a three-dimensional ultrasonic interference imaging system and method using multiple linear array acoustic sensors. Background technique [0002] At present, most ultrasound imaging systems are two-dimensional imaging systems using one-dimensional linear array probes. The so-called three-dimensional imaging systems are fake three-dimensional images obtained by splicing these two-dimensional images obtained at different times. [0003] In addition, there are also some real three-dimensional ultrasound imaging systems. These systems rely on two-dimensional area array probes to emit two-dimensional surface waves for three-dimensional imaging to obtain true three-dimensional images. However, manufacturing a two-dimensional area array probe is extremely expensive due to the complexity of the manufacturing technology and process. In addition, there are some 2.5D imaging systems that use three linear arrays of 1.5D probes. However, ...
