Vector loop diagram generation method and device based on myocardium movement locus

Abstract

The invention discloses vector loop diagram generation method and device based on myocardium movement locus. A vector loop generated by using the method can be used for evaluating myocardium functions. In the method, a speckle tracking arithmetic is used for capturing key movement points in regions of interest to generate a movement locus vector loop. The vector loop has extremely strong intuitionism on a time shaft; moreover, a doctor can tell whether pathological changes exist in the regions of interest or not at a glance by directly and synchronously displaying the rules of the myocardium movement locus vector loop.

Description

technical field [0001] The invention relates to an ultrasonic image tracking technology in the field of medical equipment, in particular to a method and device for generating a vector loop diagram based on a myocardial motion trajectory. Background technique [0002] Tissue tracking of ultrasonic cardiac images is a new technology based on tissue Doppler imaging. It can evaluate the systolic and diastolic functions of the myocardium by measuring the atrioventricular plane displacement. In addition to evaluating the overall function of the heart, it is mainly used to evaluate Therefore, it is of great significance in the early detection of myocardial ischemia, the evaluation of the viability of infarcted myocardium, and the prediction of the prognosis of heart disease.

Problems solved by technology

[0003] The existing echocardiographic evaluation methods are mainly gray-scale display methods. Recently, there have been function curve representation methods such as velocity and acceleration, and there are also speckle motion display process representation methods based on speckle tracking. However, these evaluation methods are not intuitive. It is impossible to see the movement of the characteristic interest area at a glance

There are also some companies, such as phil ips, etc., who use the method of expressing the instant motion vector of each point in the area of ​​interest at each moment. However, this method can only know the instantaneous motion vector of each point in the ring area of ​​​​interest at the same time, but cannot intuitively express a certain The movement change of the overall movement of the region on the time axis
