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.
