Abstract
(EN)
Multimodal imaging apparatus and methods include a rotatable gantry system with multiple sources of radiation comprising different energy levels (for example, kV and MV). Fast slip-ring technology and helical scans allow data from multiple sources of radiation to be combined or utilized to generate improved images and workflows, including for IGRT. Features include increasing the precision of spatial registrations between respective image sets to allow more precise radiation treatment delivery, reducing image artifacts (e.g., scatter, metal and beam hardening, image blur, motion, etc.), and utilization of dual energy imaging (e.g., for material separation and quantitative imaging, patient setup, online adaptive IGRT, etc.).
(FR)
L'invention concerne un appareil et des procédés d'imagerie multimodale comprenant un système de portique rotatif avec de multiples sources de rayonnement comprenant différents niveaux d'énergie (par exemple kV et MV). Une technologie à bague collectrice rapide et des balayages hélicoïdaux permettent de combiner ou d'utiliser des données provenant de multiples sources de rayonnement pour générer des images et des flux de production améliorés, y compris pour l'IGRT. Des caractéristiques comprennent l'augmentation de la précision des enregistrements spatiaux entre des ensembles d'images respectifs pour permettre une administration plus précise d'un traitement par rayonnement, la réduction des artefacts d'image (par exemple diffusion, durcissement du métal et du faisceau, flou de l'image, mouvement, etc.) et l'utilisation d'une imagerie à double énergie (par exemple pour une séparation des matériaux et une imagerie quantitative, une configuration de patient, une IGRT adaptative en ligne, etc.).
