Measurement method and system for obtaining arteriosclerosis index based on ultrasound equipment

Abstract

The invention provides a measurement method and configuration system for obtaining an arteriosclerosis index based on ultrasonic equipment. The measurement method includes the steps that two measurement points P1 and P2 at different measurement positions are arbitrarily acquired, and extension distance L between the two measurement points P1 and P2 is recorded; an R peak of an ECG signal is used as a time synchronization signal to obtain measurement time difference delta T between the two measurement points; a pulse wave propagation velocity PWV is obtained based on the extension distance L and the measurement time difference delta T; PWV = L / delta T; and the arteriosclerosis index D is obtained according to the pulse wave propagation velocity PWV, and D = (3.57 / PWV)<2>. According to the measurement method and system for obtaining the arteriosclerosis index based on the ultrasonic equipment, the R peak of the ECG signal is used as the time synchronization signal to calculate the measurement time difference between the two measurement points, and then the arteriosclerosis index is obtained. The calculation accuracy is improved and the measurement cost is reduced without introducingother equipment.

Description

technical field [0001] The invention belongs to the technical field of medical ultrasound, and mainly relates to a measurement method and system for obtaining an arteriosclerosis index based on ultrasound equipment. Background technique [0002] Cardiovascular disease is a major disease that seriously endangers human health, and arteriosclerosis is the common pathophysiological basis of most cardiovascular diseases. Arteriosclerosis in any part of the body may lead to ischemic function in the corresponding area, such as coronary heart disease, Stroke etc. Therefore, knowing the degree of hardening of the arteries is the key to the prevention and treatment of cardiovascular diseases. [0003] Today's arteriosclerosis detection equipment is mainly divided into two types: invasive detection and non-invasive detection. Invasive detection equipment mainly uses angiography to detect the degree of arteriosclerosis. However, detection equipment based on arteriography is an invasive...

AI Technical Summary

Problems solved by technology

[0003] Today's arteriosclerosis detection equipment is mainly divided into two types: invasive detection and non-invasive detection. Invasive detection equipment mainly uses angiography to detect the degree of arteriosclerosis. However, detection equipment based on arteriography is an invasive operation. It has the characteristics of complex detection, high price and low sensitivity

Non-invasive testing equipment will use ultrasonic imaging-based vascular compliance testing and other methods, which also have problems such as high cost, complicated operation, professional guidance, and not conducive to portable monitoring.
