Abstract

L'invention fournit un dispositif de maintien de sujet qui immobilise de manière suffisamment sûre le corps d'un sujet lors d'une thérapie par faisceau de particules. Le dispositif de l'invention est équipé d'un accessoire d'immobilisation de sujet (14) qui immobilise sur une table de support de sujet (12) le sujet (8) supporté sur cette dernirère. L'accessoire d'immobilisation de sujet (14) est équipé d'un sac (28) hermétique qui recouvre de manière tubulaire une partie ou l'ensemble du corps du sujet (8). Ce sac (28) est rempli dans une partie interne (28i) d'une pluralité de matériaux particulaires, et cette partie interne (28i) est soumise à une pression négative, les variations de forme sont ainsi empêchées. L'accessoire d'immobilisation de sujet (14) est équipé de fermetures autoagrippantes (22a, 22b) et de parties liaison (24a, 24b) qui servent d'élément d'immobilisation pour immobiliser une position relative du sac (28) sur la table de support de sujet (12), et sa partie interne (28i) est soumise à une pression négative telle que l'air est évacué de la partie interne (28i) du sac (28) recouvrant de manière tubulaire le sujet (8), ainsi, les variations de forme du sac (28) sont empêchées, et le corps du sujet (8) ainsi recouvert peut être maintenu de manière sûre.
