To examine a cerebrovascular disease non-invasively and accurately.
The variation of the quantity of cerebral blood, and variation of blood pressure and/or heart rate are measured, and the hardness of cerebral blood vessels and the change of the hardness are evaluated based on the characteristics of the low-frequency component of the variation, so that the region of the disease and the dangerous region are estimated and displayed. The living body measurement system comprises: a cerebral blood quantity measuring part for measuring the quantity of local cerebral blood of a subject; a blood pressure/heart rate measuring part for measuring the blood pressure and/or heart rate of the subject; an analysis part for analyzing signals measured by the cerebral blood quantity measuring part and blood pressure/heart rate measuring part; and an extraction part for extracting the information on the state of the local cerebral blood vessel of the subject based on the output of the analysis part. The result of measurement by the cerebral blood quantity measuring part and/or blood pressure/heart rate measuring part, or the result of analysis by the analysis part, or the result of extraction by the extraction part is displayed.
