Abstract

L'invention concerne un procédé permettant d'utiliser la tomographie optique diffuse, l'oxygène et un colorant, chez un patient souffrant d'un accident vasculaire cérébral, ou chez un patient dont on suspecte qu'il souffre d'un accident vasculaire cérébral, afin de détecter les événements ischémiques ou les saignements dans l'encéphale.
