Blood vessel of brain circulation kinetic analysis method and apparatus

Abstract

The invention relates to a brain vascular blood circulation dynamic analysis method and the apparatus thereof. According to the cerebral circulation vascular bed anatomical model, an equivalent network model which comprises 12 pipeline units simulating the brain circulation blood dynamics is built, and the relevant parameter calculation formulas are confirmed, by utilizing the formulas, the flow rate waveform and the value inside the cartid artery, the pressure waveform, the blood pressure of the body, the diameter of the blood vessel, the flow rate waveform and the valve of the vertebral artery and the front, the middle and the rear parts on two sides inside the skull, and the characteristic and the parameter of the cartid artery and each blood vessel section inside the skull can be determined, the apparatus designed by the invention can be performed, the detecting system comprises the vessel diameter detecting of the cartid artery outside the skull, the blood pressure detecting, theblood flow rate detecting of the cartid artery outside the skull, the pressure waveform detecting of the cartid artery outside the skull, and the blood flow rate detecting on the artery inside the skull; the control system comprises a control module and a power supply module; the calculation and analysis system comprises a host computer, a peripheral equipment, and an analog-digital converter, the invention can fully analyze the brain circulation dynamic characteristic, thereby having notable effect on the early stage and the ultra early stage diagnosis and therapy of the brain vascular illness.

Description

[technical field] [0001] The invention belongs to the field of medical technology, and relates to a method for analyzing the dynamics of cerebrovascular circulation and a clinical analysis instrument designed according to the method. [Background technique] [0002] A large number of clinical and animal experiments have shown that in the early stage of many cerebrovascular diseases, the dynamic parameters of cerebrovascular circulation often have significant changes, and these dynamic changes are often significantly earlier than the morphological changes. For those with abnormal early kinetic parameters, their kinetic parameters may return to normal after active prevention and treatment. Therefore, accurate and non-invasive detection of cerebrovascular hemodynamic parameters is of great significance not only for the early diagnosis of cerebrovascular diseases and the evaluation of therapeutic effects of cerebrovascular diseases, but also for the physiological and pathological...
