Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0065] Before describing the embodiments of the present invention in detail, a brief description of the pulse wave involved in the embodiments of the present invention will be given first.

[0066] Such as figure 1 as shown, figure 1 shows the signal trace of the pulse wave within one cycle, figure 1 Four feature points (A, B, C, D, respectively) and three bands (AB, BD, DC, respectively) are shown in .

[0067] Generally speaking, the pulse wave signal of healthy people has steep rising and falling edges. This is because healthy people have better vascular function, less vascular resistance, and higher blood flow velocity. At the same time, tidal wave B is not prominent in the pulse wave signal of a healthy person. When the aortic...

Abstract

The invention discloses a pulse Doppler image processing method and device, which belongs to the technical field of image processing. The method comprises the steps that the grayscale value of a pixelpoint with the grayscale value not lower than a threshold in a pulse Doppler image is set to be 1, and the grayscale value of other pixel points is set to be 0; for any one column of pixel points, apixel is sequentially acquired in the order from the first row to the M-th row until the pixel point with the grayscale value of 1 is acquired, and the pixel point with the grayscale value of 1 is determined as the first position corresponding to the any one column; a first image and a second image are generated; the grayscale value of the pixel point at the first position of the first image is 1,and the grayscale value of other pixel points is 0; the grayscale value of pixel points above the first position corresponding to the any one column in any one column of pixel points in the second image is 0, and the grayscale values of other pixel points is 1; and the first image and the second image are used to generate a pulse wave trace. The problems of heavy workload and complicated operation of pulse wave trace description in the related art are solved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a pulse Doppler image processing method and device. Background technique [0002] Currently, medical testing equipment (eg, ultrasound equipment) on the market can use the principle of the Doppler effect to detect blood flow to obtain pulsed Doppler images. Experienced physicians can use the trackball of the ultrasound equipment to manually trace the trajectory of the pulse wave in the pulse Doppler image, and then analyze the pulse wave trajectory to obtain blood flow information, such as blood flow velocity, intima-media thickness of blood vessels, and Blood flow information such as maximum blood flow velocity and degree of arteriosclerosis of blood vessels. [0003] However, it takes 15 to 20 minutes for an experienced physician to draw a pulse wave trajectory. If an operation error occurs during one drawing, it needs to be redrawn, which is a heavy workload and cumb...
