Abstract
Limagerie peut être réalisée au moyen dun système de traitement de radiothérapie en mégavolts (MV). Le faisceau délectrons dirigé vers une zone Z faible produit un faisceau de cône dimagerie. Le cône peut être dune forme telle à se conformer aux projections de volumes dintérêt chez un sujet. Le remplissage dimage peut être réalisé pour réduire des objets dans les volumes dintérêt. Les données dimage de remplissage peuvent être dérivées de radiographies reconstruites numériquement.
