Ultrasonic contrast imaging method and device

Abstract

The invention provides an ultrasonic contrast imaging method and device. The method comprises the steps that a first ultrasonic probe is controlled to emit first ultrasonic waves to a liver area of a target object; a first ultrasonic image is generated based on a first ultrasonic echo signal, and an area of interest on the first ultrasonic image is acquired to determine a position area to be subjected to contrast imaging in the liver area; under the condition that a contrast agent is injected into the target object, the first ultrasonic probe is controlled to emit second ultrasonic waves to the position area; after the contrast agent is injected and when preset conditions are met, a second ultrasonic probe is controlled to emit third ultrasonic waves to a portal vein area of the liver area, wherein the third ultrasonic waves are used for bursting microbubbles generated by the contrast agent in the portal vein, and emission of the second ultrasonic waves and emission of the third ultrasonic waves are conducted alternately or conducted independently; and a contrast image is generated based on a second ultrasonic echo signal. According to the method and device, pure hepatic artery ultrasonic contrast imaging can be achieved.

Description

technical field [0001] The present invention relates to the technical field of ultrasound imaging, and more particularly to a method and device for contrast-enhanced ultrasound imaging. Background technique [0002] In modern medical imaging examinations, ultrasound technology has become the most widely used, most frequently used examination method and the fastest popularization and application of new technologies due to its high reliability, fast and convenient, real-time imaging, and repeatable examinations. The development of some new ultrasound technologies has further promoted the application of ultrasound imaging in clinical diagnosis and treatment. [0003] Ultrasonic waves will scatter when they encounter scatterers, and the intensity of the scattering is related to the size and shape of the scatterers and the difference in acoustic impedance with surrounding tissues. Although the blood contains tangible substances such as red blood cells, white blood cells, and pla...

AI Technical Summary

Problems solved by technology

In the current liver contrast-enhanced ultrasonography examination, although there is a certain time interval between the contrast images of the arterial phase and the portal venous phase, the time interval is very short. Microbubbles in the portal vein begin to appear, so the image quality of hepatic arteriography, especially in the late arterial stage, will be severely disturbed by microbubbles of contrast agent in the portal vein

According to the existing liver contrast-enhanced ultrasound imaging technology (intravenous injection of contrast agent), the hepatic arteriography image obtained by the doctor and the hepatic arteriography displayed by the method of injecting contrast agent directly through the hepatic artery in the operating room (invasive method) The image is not exactly the same

The current hepatic contrast-enhanced ultrasonography technology is still unable to realize pure hepatic arteriography imaging in the true sense, and cannot present the complete arterial enhancement process
