Ultrasonic image reconstruction method and system

Abstract

The invention discloses an ultrasonic image reconstruction method and system. The method for establishing the image reconstruction network model includes: obtaining a training sample set; the training sample set includes a plurality of sample pairs, and each sample pair includes a group of ultrasonic radio frequency training data obtained according to natural images and / or medical images and a corresponding training image. grayscale image. Build a generative confrontation network model, which includes a generator and a discriminator. The training sample set is used to train the generative confrontation network model, so that the generative confrontation network model reaches Nash equilibrium, and the generator in the Nash equilibrium state is used as the image reconstruction network model for ultrasound image reconstruction. The present invention uses natural images and medical images whose resolution is much higher than that of ultrasonic images as the data basis for training the generated confrontational network model, and then automatically learns and optimizes parameters through the generated confrontational network model to obtain the mapping relationship from the original data to the ultrasonic image, which can effectively Improve image quality.

Description

technical field [0001] The invention relates to the field of imaging, in particular to an ultrasonic image reconstruction method and system. Background technique [0002] Ultrasound imaging is a convenient, real-time, non-destructive imaging method. This method uses the acoustic impedance difference information of different parts inside the detected object carried in the ultrasonic echo signal to perform imaging. The traditional ultrasonic imaging process is divided into two steps. The first step is to obtain ultrasonic radio frequency (Radio Frequency, RF) signals from the ultrasonic transducer, and the second step is to use the RF signals to generate ultrasonic images, that is, ultrasonic image reconstruction. Ultrasound radio frequency signal is the original signal in the process of ultrasound imaging, which is easily disturbed and affects the imaging quality. Moreover, the ultrasonic image reconstruction process involves multiple steps, and each step needs to set many ...

Ultrasound radio frequency signal is the original signal in the process of ultrasound imaging, which is easily disturbed and affects the imaging quality

Moreover, the ultrasonic image reconstruction process involves multiple steps, and each step needs to set many parameters. Most of the current methods are to set the parameters of each step based on experience, and the effects of parameter adjustments in each step affect each other. An efficient way to overall plan these parameters, resulting in poor final image quality
