Analytical system and analytical method for property of blood vessel of brain and blood flow behavior

The invention belongs to the human biological parameter detection and analysis system field, and particularly relates to a brain blood vessel feature and blood flow characteristics analysis system and an analysis method thereof. The analysis system comprises a human biological signal reception part, a main processing part, a control input part, and an output part. Human biological signals collected by the human biological signal reception part are transmitted to the main processing part for data processing after A/D transformation and then are outputted by the output part, and the control input part sends corresponding control signals into the main processing part to complete corresponding data processing. The analysis method comprises: 1) a construction stage of basic data of the brain blood vessel system feature; 2) an evaluation preparation stage of the brain blood vessel system; 3) indirectly working out the elasticity cardinal number of each blood vessel branch displaying feature variance in front, middl
