Artery intracavity ultrasound imaging method, artery intracavity ultrasound imaging device, equipment and artery intracavity ultrasound imaging system

The invention discloses an artery intracavity ultrasonic imaging method. The withdrawing speed of a probe is determined according to relative speed change data between a target artery section and an ultrasonic probe when the ultrasonic probe is static, so that the influence of the movement process of the artery cavity along with the heartbeat on the withdrawing image acquisition process of the probe can be reduced; loss of useful data can be avoided while repeated imaging is avoided; an appropriate number of arterial cavity images are enabled to be acquired; the occurrence of image distortion is avoided; the accuracy of withdrawing image acquisition is improved, so that a reliable length value is provided for an arterial intervention doctor in the arterial intervention treatment process, and the accuracy of the arterial lesion length measured according to artery intracavity ultrasonic imaging is improved; and the diagnosis and treatment effect can be effectively improved. The invention also discloses an arter
