Ultrasonic imaging device and method for detecting vascular wall shear index by using ultrasound

Abstract

The invention provides an ultrasonic imaging device, a method for detecting a vascular wall shear index by using ultrasound and a computer readable storage medium. The method comprises the following steps: emitting ultrasonic waves to a region of interest containing a blood vessel (S701, S801-802, S901); receiving ultrasonic waves, and obtaining echo signals (S702, S803, S902); obtaining an ultrasound image according to the echo signal (S703, S804, S903); according to the echo signal, obtaining a particle flow velocity of a plurality of points in the blood vessel, the particle flow velocity comprising a blood flow velocity and direction (S704, S805, S904); determining a blood vessel wall in the ultrasound image (S705, S806, S905); obtaining a position to be measured on the blood vessel wall (S706, S807, S905); calculating a vascular wall shear index (S707, S808, S906) at the position to be measured according to the mass point jet velocities of a plurality of points near the position to be measured (S707, S808, S906); and displaying the ultrasound image and the vascular wall shear index (S708, S809). According to the ultrasonic imaging device and method, the shear index of the blood vessel wall can be detected at low cost.

Description

[0001] This application is a divisional application of an invention patent application with an application date of April 28, 2017, an application number of 201780018341.3, and an invention title of "ultrasonic imaging equipment and a method for detecting vascular wall shear index using ultrasound". technical field [0002] The present invention relates to an imaging method, in particular to an ultrasonic imaging device and a method for detecting a blood vessel wall shear index using ultrasound applied to the ultrasonic imaging device. Background technique [0003] The shear index of the vessel wall, such as WSS (Wall Shear Stress, shear stress of the vessel wall), is a parameter recognized in the medical field and related to arteriosclerosis. The vessel wall shear index is generally related to the gradient of the blood flow velocity component along the tangential direction of the vessel wall near the vessel wall. Therefore, when calculating or detecting the value of WSS, it ...

Problems solved by technology

However, the detection method based on phase-contrast magnetic resonance angiography takes a long time, and the equipment is expensive, and it will bring a lot of inconvenience to patients and doctors during the inspection, for example, it will lead to poor inspection comfort and requires ECG (Electrocardiograph, electrocardiogram). ) calibration, the signal may be interfered, etc.
