Ultrasonic angiography image analysis method and system thereof

Abstract

The invention provides an ultrasonic angiography image analysis method and system. The method comprises the following steps: obtaining a dynamic medical image meeting a DICOM (Digital Imaging and Communications in Medicine) standard; selecting an initial region of interest from the dynamic medical image; calculating a plurality of corresponding analysis parameter values of each pixel point of the initial region of interest, and carrying out colorful encoding on the analysis parameter values to obtain colorful codes of different parameters of the initial region of interest; selecting a current region of interest of the colorful codes; obtaining a parameter analysis curve of the current region of interest and a contrast speed analysis curve; providing an analysis result of the current region of interest. Compared with the prior art, the method can be used for carrying out the colorful encoding on the plurality of corresponding analysis parameter values of each pixel point, so that contrast parameters can be accurately quantified, and furthermore, accurate reference and differential diagnosis can be provided for doctors. The current region of interest can also be subjected to parameter analysis and speed analysis on the basis of the initial region of interest, and the clinical diagnosis can be facilitated.

Description

technical field [0001] The present invention relates to the technical field of contrast-enhanced ultrasound analysis, in particular to a method and system for analyzing contrast-enhanced ultrasound images. Background technique [0002] Ultrasonic instrument, also known as ultrasonic instrument, is a medical instrument developed based on the principle of ultrasound. It is an ultrasonic diagnostic device used in medical imaging systems in the fields of medical clinics, diagnosis, and hygiene. With the popularization of conventional gray-scale ultrasound and color Doppler ultrasound equipment, the role and value of these two ultrasound equipment in clinical diagnosis and treatment have become increasingly apparent, and they have become indispensable in clinical diagnosis. [0003] However, problems that cannot be solved by these two ultrasonic instruments often appear in clinical diagnosis, such as the display of low-speed blood flow and the detection of small blood vessels, be...

AI Technical Summary

Problems solved by technology

[0008] 1) If the enhancement inside the area is uneven, such as necrotic areas, or honeycomb, etc., the analysis results of this area are meaningless;

[0009] 2) In hemangioma, etc., there are features such as ring enhancement, and the time displayed by the average intensity will not be able to show the ring enhancement in this area;

[0010] 3) In fields such as prostate puncture intervention, because the difference between regions is very small, it is impossible to determine the region to be punctured by using the region analysis method;

[0011] 4) The current regional analysis only involves the analysis of the strength, not the analysis of the change of the strength, that is, the analysis of the velocity; and
