Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a method for automatically positioning the sampling frame by Doppler ultrasound, which uses the Doppler ultrasound system to automatically locate the sampling frame according to the image information. The device for positioning the sampling frame reduces the operational difficulty of Doppler ultrasound examination, and solves the problem that the operator cannot quickly and accurately identify blood vessels in the ultrasound image and set the position of the sampling frame in C mode, and often has to operate repeatedly. Questions that waste a lot of time

Embodiment

[0040] Generally speaking, the rows and columns of the ultrasound image are powers of 2, such as 128, 256 and so on. Assume an image with 128 rows x 256 columns of pixels. The present invention takes linear Doppler ultrasonic scanning as an example, the scanning area is rectangular, and the sampling frame is rectangular. The implementation steps are as follows.

[0041] S1, obtain B-ultrasound black and white images by scanning, and filter E0 , from the black-and-white image data to filter out low-brightness pixel point sets, which include flowing blood, almost non-flowing body fluids and some noises.

[0042] S2.1, the default sampling frame size is 48x96 pixels.

[0043] S2.2, divide the entire B-ultrasound image area into 8x8 grids, each grid size is 16x32 pixels, so the sampling frame is equivalent to 3x3 grid size.

[0044] S3.1, take the upper left vertex of each grid as a reference point, and coincide with the upper left vertex of the sampling frame. Then count the ...

Abstract

The invention discloses a method for automatically positioning a sampling frame via Doppler ultrasonic wave. A sampling frame is automatically positioned by a Doppler ultrasonic system according to image information. Positions of the sampling frame can be automatically set and adjusted according to imaging data, so ultrasonic imaging equipment can quickly find a position with rich blood flow information, and therefore blood vessel check time can be reduced and operation for Doppler ultrasonic measurements by an operator with less experience can be facilitated; when the same part is checked foreach person to be checked, standards can be built; the algorithm can be combined with artificial intelligence, so automatic scanning can be realized; and automatic check becomes possible.

Description

technical field [0001] The invention relates to the field of ultrasound medical detection, in particular to a method for automatically positioning a sampling frame by Doppler ultrasound. Background technique [0002] Ultrasound imaging is an important direction in medical imaging and is mainly used in clinical diagnosis. It observes the audiovisual manifestations of human tissue and organ morphology and function changes through the study and application of ultrasonic acoustic characteristics, optical characteristics, imaging principles, anatomical, physiological, and pathological characteristics of human tissues and organs, and basic knowledge of clinical medicine, and then analyzes and summarizes them. , to explore the occurrence and development of diseases, so as to realize the diagnosis and treatment of diseases. As a non-invasive imaging method, ultrasound imaging has the advantages of strong real-time performance, low price, and convenient operation, and has become an ...
