Problems solved by technology

[0006] At present, the cerebral circulation analyzers at home and abroad can only calculate and analyze the dynamic parameters reflecting the cerebral circulation function, and cannot make an early diagnosis of atherosclerosis, the main cause of cerebrovascular diseases; In terms of calculation, most of them do not detect or use low-accuracy A-ultrasound or M-ultrasound to detect the diameter of blood vessels, which brings great errors to the analysis results

Embodiment Construction

[0048] Further illustrate the present invention below in conjunction with accompanying drawing.

[0049] see figure 1 It can be seen that the data flow of the cerebrovascular system function and the cerebral circulation dynamics analysis method of the present invention is as follows: first, the B-type ultrasonic detection module is used to detect the transverse and longitudinal tomographic images of the carotid artery, and the image information is processed to obtain the carotid artery. Arterial imaging data and vessel diameter D; then apply the continuous wave Doppler blood velocity waveform detection module to detect the carotid artery blood velocity waveform and value: V(t), and then combine the vessel diameter data to calculate Carotid artery blood flow waveform and value: Q(t); apply the blood viscosity detection module to detect blood viscosity η, and then combine the carotid artery blood flow waveform and value to calculate the shear stress index of the carotid artery w...

Abstract

The invention discloses a cerebrovascular system function and brain recirculation dynamic analysis method, wherein iconographical index and tangential stress index for reflecting cerebrovascular atherosclerosis degree and arteria carotis blood vessel are added into the analytical method, these two indexes can perform early diagnosis and analysis to atherosclerosis and comprehensive analysis for the prevention and early stage diagnosis for cerebrovascular diseases. The invention also discloses the related analytic instrument based on the method for detecting blood vessel diameter by employing type B supersonic detection, which can improve detecting accuracy substantially.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a method for analyzing the function of the cerebrovascular system and dynamics of cerebral circulation and an analysis instrument designed according to the method. Background technique [0002] Atherosclerosis is a chronic disease that seriously endangers human health. It is characterized by lipid deposition in the intima and subintima of arteries and their branches, accompanied by the migration of smooth muscle cells in the middle layer to the subintima to proliferate. , to thicken the intima, forming a yellow or gray-yellow plaque like atheroma. In recent years, with the increasing development of my country's economic construction and the continuous improvement of people's living standards, the incidence of this disease has a tendency to increase significantly in our country. According to the results of autopsy, the detection rates of coronary artery and aortic atheroscleroti...
