Post treatment device and method of M-shaped ultrasound image of common carotid artery

Abstract

The invention discloses a post treatment method of an M-shaped ultrasound image of a common carotid artery. The post treatment method comprises the following steps: after an ultrasonic wave is longitudinally cut and imaged, M-shaped ultrasound imaging is executed by selecting a sample line to obtain the M-shaped ultrasound image, an artery lumen region in the image is judged, and a row of pixel points transversely passing through the entire lumen region is used as a canal diameter measurement reference row; a mask mtehod is adopted to search in the near-field and far-field directions of each pixel point in the canal diameter measurement reference row, the demarcation point of the intima and the canal diameter is confirmed, the canal diameter change data of the common carotid artery positioned at the sample lines in several cardiac cycles and pulsed along the heart is obtained through calculation and the pulse wave velocity is estimated. The invention discloses a device for realizing the method. According to the post treatment method, the pulse wave velocity in the common carotid artery can be measured by a computer, the precision is obviously improved and the transfer efficiency is greatly promoted.

Description

technical field [0001] The invention relates to a post-processing device and method for an M-mode ultrasonic image of a common carotid artery, in particular to an image processing device and method in image measurement. Background technique [0002] Because the physiological condition of the common carotid artery is closely related to human health, the ultrasonic examination of the common carotid artery is of great significance for the screening of related diseases. [0003] The ultrasonic examination of the common carotid artery is mainly to collect ultrasonic images through ultrasonic imaging equipment, and the image signal output by the ultrasonic imaging equipment is first converted from analog signal to digital signal, and then the computer is used for calculation and processing, displaying the processed image, and outputting the measured parameters data. [0004] After imaging, the ultrasound operator can freeze and measure the image on the ultrasound imager, but such...

AI Technical Summary

Problems solved by technology

[0004] After imaging, the ultrasound operator can freeze and measure the image on the ultrasound imager, but such operations are limited to the ultrasound imaging instrument, which is not conducive to the transmission of image information through the image transmission network within the medical institution, and the efficiency is low

[0005] The measurement operation on the ultrasonic imaging equipment is generally performed manually by the operator, and the accuracy is not high based on the naked eye reading the picture

The pulse wave propagation velocity cannot be directly measured on the ultrasound image, and the operator needs to combine the blood pressure data for cumbersome calculations, which is inefficient
