Abstract

L'invention porte sur un support (160), qui a au moins deux unités de montage de sonde (171). Des sondes d'émission de lumière (12) qui rayonnent une lumière à partir de la pointe, ou des sondes de réception de lumière (13), qui reçoivent une lumière à partir de la pointe, sont insérées dans les unités de montage de sonde (171), et le support (160) est monté sur la tête du patient. Ce support comporte une unité de tronc linéaire (162) s'étendant dans une première direction, et au moins deux ramifications linéaires (161) s'étendant dans une seconde direction différente de la première direction, et les unités de montage de sonde (171) sont formées à l'extrémité des ramifications (161).
