Abstract

The invention discloses a blood flow automatic measurement method and device based on an ultrasonic image, and the method comprises the steps: obtaining a blood vessel ultrasonic image of a target object in a preset time under a first detection mode, and obtaining an ultrasonic Doppler image of the target object in a preset time under a second detection mode; identifying the blood vessel wall position of the blood vessel tissue in the target object according to the blood vessel ultrasonic image; acquiring the blood flow velocity of the vascular tissue within a preset time according to the ultrasonic Doppler image; and calculating blood flow information of the vascular tissue according to the position of the vascular wall and the blood flow velocity within the preset time. According to theblood flow measurement mode, the operation process is simpler, medical staff do not need to manually label and switch image modes back and forth, and the examination efficiency is improved; and meanwhile, the blood flow is calculated by utilizing the blood vessel diameter data and the blood flow speed data within the preset time, so that the blood flow calculation result is more robust, random interference caused by instantaneous measurement is reduced, and the measurement result is more accurate.

Description

technical field [0001] The invention relates to the technical field of blood flow measurement, in particular to a method and device for automatic measurement of blood flow based on ultrasonic images. Background technique [0002] Ultrasound imaging is an important means of medical diagnosis. Doctors can obtain different types of diagnostic information through different modes of ultrasound images. Blood flow is an important indicator for evaluating vascular function, and can indirectly evaluate the function of the human circulatory system. Therefore, clinically, measurement of blood flow is used to assess vascular performance. [0003] In B mode, the ultrasonic device can obtain information such as the shape, diameter and position of blood vessels; in PW mode, the ultrasonic device can obtain blood flow velocity information. For human blood vessels, the combination of the two can obtain the blood flow information of the corresponding position of the blood vessels. At prese...
