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

Abstract

The invention provides an afterprocessing method of ultrasonic longitudinal-cutting images of the common carotid artery. The afterprocessing method includes determining arterial lumen positioning points, intima positioning points and tunica media positioning points in the ultrasonic longitudinal-cutting images of the common carotid artery, tracking the intima and the tunica media according to the intima positioning points and the tunica media positioning points, and determining the intima boundary and the tunica media boundary and thereby calculating the thickness of the intima and the tunica media of the artery according to boundary position information. The invention further provides a device implementing the method. By the afterprocessing method and device, computer measuring of the thickness of the intima and the tunica media in the carotid artery is realized, accuracy is remarkably improved, and transmission efficiency is greatly improved.

Description

technical field [0001] The invention relates to a post-processing device and method for ultrasonic longitudinal section images of 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] Ultrasonic examination of the common carotid artery mainly collects ultrasonic images through ultrasonic imaging equipment, and the image signals output by the ultrasonic imaging equipment are first converted from analog signals to digital signals, and then computer is used for calculation and processing, displaying the processed images, and outputting the measured parameters data. [0004] After imaging, the ultrasound operator can freeze and measure the image on the ultrasound imager, but su...
