Problems solved by technology

In addition to the disadvantage of low frame rate, the existing line-by-line scanning contrast imaging technology can only show the difference in microbubble intensity on the image, and the speed difference of contrast agent microbubbles in the cut plane cannot be displayed intuitively. It is impossible to accurately determine the velocity of contrast agent microbubbles through ultrasound-contrast images

Abstract

The present application discloses an ultrasound contrast imaging method comprising: transmitting an unfocused wave to a target region containing microbubbles in a plurality of directions; receiving echo signals of the unfocused wave; and selecting an echo signal corresponding to at least a portion of the angles in a plurality of angles from the echo signals; and generating a contrastographic picture based on the selected echo signal and displaying the same in color codes. The application also discloses an ultrasound imaging system.

Description

technical field [0001] The present invention relates to an ultrasound imaging method, in particular to an ultrasound contrast imaging method and an ultrasound imaging system applying the ultrasound contrast imaging method. Background technique [0002] Ultrasound contrast agent microbubbles can enhance the intensity of reflected echoes. Its diameter is very small, about the size of blood cells, and can diffuse to various organs of the human body with human blood, and the movement of contrast agent microbubbles has significant nonlinear characteristics. With the maturity of contrast-enhanced ultrasound imaging technology based on nonlinear features, contrast-enhanced ultrasound imaging has been widely used clinically in the differentiation, diagnosis and treatment of benign and malignant tumors. Since the contrast agent diffuses with the blood, the velocity of the contrast agent microbubbles observed on the ultrasound-contrast image reflects the blood flow velocity in the cut...
