Abstract

Appareil de radiochirurgie stéréotactique permettant d'éliminer les désalignements dus à des imprécisions et à des déflexions mécaniques d'une tête d'accélérateur linéaire émettant un rayonnement que l'on fait osciller à travers un arc, comprenant une structure de guidage et de support (54) comportant un premier système de support destiné à faire tourner avec précision un collimateur (32) à travers un arc précis dans un plan vertical (30) par rapport à un point central prédéterminé (34) dans le plan correspondant à un emplacement de traitement. La structure comporte un second système de support à balancier (70) permettant d'accoupler le collimateur (32) à la tête (16) de sorte que la tête tournante peut entraîner le collimateur (32) à travers son arc tout en désaccouplant mécaniquement la tête du collimateur par élimination des couples de torsion et des forces qui s'exerceraient sur le collimateur à cause des imprécisions ou des déflexions mécaniques de la tête. La structure comporte un troisième système de support (86) permettant de supporter de manière rotative un pied stéréotactique (28) en vue d'une rotation autour d'un axe vertical (30) entrecroisant le point central. Comme le mouvement du collimateur (32) et la rotation du pied sont commandés avec précision par rapport au point central, l'appareil garantit que le rayonnement émanant de la tête est focalisé avec précision au point central (34) pour toutes les positions de rotation de la tête et du pied. Des agencements de liaisons mécaniques sont présentés, permettant au pied de tourner automatiquement lors de la rotation d'une table (20) de traitement de patient. Bien que les agencements de liaisons soient utilisés pour entraîner la rotation du pied, ils permettent d'éviter des imprécisions de position dans sa rotation.
