Problems solved by technology

[0002] Through three-dimensional reconstruction of a series of two-dimensional ultrasound image sequences, three-dimensional ultrasound imaging can present three-dimensional anatomical structures that cannot be presented by traditional two-dimensional ultrasound. The target will have different shapes in different motion phases. If the 2D ultrasound image sequence is directly reconstructed in 3D without any processing, the different shapes of the moving target in different phases will be mixed together, which will eventually lead to distortion of the reconstruction results. , thus affecting the diagnosis
This method must rely on auxiliary signals to complete the three-dimensional reconstruction of the moving target, and the image acquisition and processing process is relatively complicated
