Abstract

The invention discloses an ultra-high-speed ultrasonic imaging reconstruction method based on phase constraint. The method comprises the following steps: acquiring plane wave channel data through an ultrasonic machine of a linear array probe; performing beam forming on the channel data, and dividing a training set and a test set; inputting the training set into the generator network for training, and adjusting according to the effect of the test set until the reconstruction effect meets the requirement; and inputting the single-angle plane wave RF data into the trained generator network in the step 3, and taking an output result as an image reconstruction result. The method has the advantages that the quality of an ultrasonic image is improved without transmitting plane waves of multiple angles to perform coherent combination, a high-quality image close to 75-angle coherent combination can be obtained only through single-time transmission, the frame rate can theoretically reach 75 times of the 75-angle coherent combination, and phase information of coherent composite plane waves of about 75 angles is reserved, so that the two-dimensional displacement tracking effect on RF data is hardly influenced.

Description

technical field [0001] The invention relates to a reconstruction method of ultra-high-speed ultrasonic imaging based on phase constraints, and belongs to the technical field of ultra-high-speed ultrasonic imaging based on ultrasonic plane waves. Background technique [0002] Ultrasound imaging is widely used in clinical diagnosis and treatment evaluation due to its advantages of non-invasiveness, economy, and real-time display. However, traditional ultrasound imaging uses focused wave scanning. Although very high-quality B-mode images can be obtained, the frame rate is very limited, often only reaching 30 to 40 frames per second. To study rapidly changing tissue motion in the human body, higher frame rate imaging methods are required. For example, in the cardiovascular system, frame rates of several hundred hertz are required to accurately analyze tissue motion and blood flow patterns. Ultrafast ultrasound imaging can significantly improve the robustness and sensitivity of...
