Abstract

La présente invention a trait au domaine technique des dispositifs médicaux et concerne un système de radiothérapie et un procédé de commande d'entraînement associé. Le système de radiothérapie selon l'invention concerne un appareil de radiothérapie pourvu à la fois d'une tête de traitement à modulation d'intensité conforme (20) et d'une tête de traitement focalisée multi-sources (10), de sorte à réaliser un traitement collaboratif au moyen des différentes têtes de traitement (10, 20) sur un seul appareil, ce qui permet d'améliorer l'efficacité thérapeutique ainsi que l'effet thérapeutique. La tête de traitement focalisée muti-sources (10) est combinée à la tête de traitement à modulation d'intensité conforme (20), ce qui permet d'améliorer l'efficacité thérapeutique ainsi que l'effet thérapeutique. Le système de radiothérapie selon l'invention comprend un rouleau (40) et au moins deux têtes de traitement (10, 20) disposées sur le rouleau (40), lesdites deux têtes de traitement (10, 20) au moins comprenant au moins une tête de traitement focalisée multi-sources (10) et au moins une tête de traitement à modulation d'intensité conforme (20).
