Blood flow noise suppression method and device, ultrasonic equipment and readable storage medium

The invention relates to the technical field of image processing, and discloses a blood flow noise suppression method and device, ultrasonic equipment and a readable storage medium. The method comprises the following steps: acquiring an intravascular ultrasound image to be processed; performing blood vessel recognition on the intravascular ultrasound image based on a preset blood vessel recognition model to obtain a blood vessel region of the intravascular ultrasound image; wherein the preset blood vessel recognition model is obtained by training an intravascular ultrasound image sample and a blood vessel region sample; and performing blood flow noise suppression on the blood vessel region to generate a target image. By implementing the technical scheme of the invention, noise suppression can be performed on the blood vessel region, and the processing speed of noise suppression is improved, so that the blood flow noise removal efficiency of the intravascular ultrasound image is improved, and efficient blood v
