Abstract

Une plaque de base de positionnement pour radiothérapie selon l'invention comprend un siège de base (1). Le siège de base (1) présente une partie oreiller supérieur (2) et un corps de lit (3) présentant une structure en forme d'arc épousant la forme de la tête, du cou et des épaules du corps humain. Il existe une différence de hauteur verticale entre la partie oreiller supérieur (2) et le corps de lit (3) et la partie oreiller supérieur (2) est convexe vers le haut par rapport au corps de lit (3). La plaque de base de positionnement assure que le patient puisse s'allonger confortablement et peut également répondre aux exigences de changement de gradient de densité de rayons de la plaque de base de positionnement, ce qui permet de réaliser des rayons d'incidence à partir de multiples angles.
