APPARATUS AND METHOD FOR OBTAINING INFORMATION RELATING TO CEREBRAL HAEMODYNAMICS

摘要

The invention relates to an apparatus and method for obtaining information relating to cerebral haemodynamics. The inventive method comprises the following steps consisting in applying an excitation signal (Se) to the head and capturing two output signals (S1) and a second output signal (S2) with different cerebral blood flow or volume dependencies and different scalp blood flow and volume dependencies. The aforementioned signals are processed in order to obtain a result which reflects cerebral blood flow with minimum corruption by the blood flow in the scalp.
