Problems solved by technology

On the one hand, there is a problem in principle: the blood pressure and the physiological state of blood vessels are not independent, but interact with each other; difference, and the separate measurement process is cumbersome, which increases the workload of the measurement personnel and the measurement efficiency is low; the measured two parts correspond to different cardiac cycles, and the value of the measured data is limited to a certain extent

Abstract

The invention relates to a blood vessel physiological parameter measurement method and device, a computer device and a storage medium. The method comprises the steps: obtaining a first reference ultrasonic image sequence of a to-be-measured blood vessel when the to-be-measured blood vessel is not loaded and at least one group of ultrasonic image sequences of the to-be-measured blood vessel when the to-be-measured blood vessel is loaded with a preset load, and ranking to obtain a target first reference ultrasonic image sequence and at least one group of target ultrasonic image sequence in a cardiac cycle; obtaining a displacement field sequence group according to the target first reference ultrasonic image sequence and the at least one group of target ultrasonic image sequence; and inputting the preset load into a preset to-be-measured blood vessel finite element model, simulating and matching the displacement field sequence group, to obtain a cardiac cycle blood pressure change waveform and a relationship between the blood vessel elasticity modulus and the cardiac cycle blood pressure. According to the method, the blood pressure change waveform of the cardiac cycle and the blood vessel elasticity modulus can be obtained at the same time, and the blood vessel physiological parameter measurement efficiency is improved.

Description

technical field [0001] The present application relates to the field of research on vascular characteristics, in particular to a method, device, computer device and storage medium for measuring vascular physiological parameters. Background technique [0002] Blood vessels are an important part of the circulatory system, and the study of vascular properties is very important for the screening and diagnosis of many diseases. Blood vessels have a multi-layer tubular composite structure, which bears the pressure of blood vessels and the constraints of external tissues of blood vessels, so there are many parameters that affect the characteristics of blood vessels. At present, research on vascular characteristics in clinical medicine mainly includes blood pressure changes, vascular mechanical properties, etc.; traditional vascular parameter measurement includes blood pressure measurement and vascular mechanical property measurement; but the measurement of the above two parameters i...
