Composite energy Doppler blood flow imaging method and system

Abstract

The invention provides a composite energy Doppler blood flow imaging method and system. The method comprises the following steps that a plurality of scanning lines are configurated in the same frame of scanning, and a certain scanning direction is configurated for each scanning line, wherein the number N of the scanning directions is equal to or larger than two; scanning line wave beams are emitted to a blood flow to be imaged; a plurality of echo data for blood flow imaging are received, and the data are processed so as to obtain and display a corresponding energy Doppler blood flow image. According to the composite energy Doppler blood flow imaging method and system, the scanning directions are configurated for the scanning lines in the same frame of scanning so as to guarantee the effect that at least one scanning line in the scanning lines is not perpendicular to the current blood flow direction, therefore, the sensitivity of blood flow imaging is guaranteed, and the image effect of ultrasonic imaging is improved accordingly.

Description

technical field [0001] The invention relates to the field of medical ultrasound imaging, in particular to a composite imaging method and system for improving the sensitivity of energy Doppler blood flow imaging applied in the field of medical ultrasound imaging. Background technique [0002] Color blood flow imaging technology has been more and more widely used due to its superior ability to detect blood flow, especially power Doppler blood flow imaging (referred to as blood flow imaging). Clinically, the basic requirement for ultrasonic color flow imaging is the sensitivity of blood flow detection, especially in the detection of benign and malignant tumors. If the blood flow that should be detected is not detected due to the insensitivity of blood flow detection, It will affect the judgment of the ultrasound doctor and cause misdiagnosis or missed diagnosis. [0003] For blood flow imaging, when the direction of the ultrasound beam is perpendicular to the flow direction of...

Problems solved by technology

[0004] However, the above solution requires medical staff to manually adjust the ultrasound equipment to ensure the sensitivity of blood flow imaging, which not only increases the burden on medical staff, but also inevitably causes human errors; in addition, if the blood flow in a section has multiple directions, such as For the blood flow of small organs (thyroid gland, breast or testis, etc.), doctors cannot predict the direction of these small blood flows. No matter which direction the doctor deflects the sound beam, it can only improve the direction of blood flow that is not perpendicular to the direction of the sound beam. The sensitivity of blood flow detection is greatly reduced, and the sensitivity of blood flow perpendicular to the direction of the acoustic beam is greatly reduced, which cannot maximize the sensitivity of blood flow imaging
