Title
(EN) APPARATUS AND METHODS FOR SCALABLE FIELD OF VIEW IMAGING USING A MULTI-SOURCE SYSTEM
(FR) APPAREIL ET PROCÉDÉS D'IMAGERIE À CHAMP DE VISION ÉCHELONNABLE EN UTILISANT UN SYSTÈME À SOURCES MULTIPLES
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 large field-of-view (LFOV) MV imaging, kV region-of-interest (ROI) imaging, and scalable field-of-view (SFOV) dual energy imaging.

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. Les caractéristiques comprennent une imagerie MV à grand champ de vision (LFOV), une imagerie de région d'intérêt (ROI) kV et une imagerie à double énergie à champ de vision échelonnable (SFOV).
