[A technique of MRI signal processing for functional imaging].
Recent works show the possibility of MRI to study brain functionalities. Today, treatment relies essentially on addition and subtraction of images accumulated during rest and activity periods. But this technic is not discriminating and we have developed a software to see and treat images with filtering algorithm and statistical analysis of signal. The first results are given. Perfections are possible and are being realized.
