Calcul de dose de radiothérapie à partir de tomographies coniques : état de l’art

Abstract: En radiothérapie externe, la planification dosimétrique est basée sur des images tomodensitométriques (CT). Une conversion des nombres Hounsfield, contenus dans ces images, en densité électronique (ou physique) est nécessaire pour réaliser un calcul de dose tenant compte des hétérogénéités. Dans un processus d'IGRT (Image Guided Radiotherapy), le Cone Beam CT (CBCT) est utilisé pour visualiser et recaler les structures anatomiques. Le calcul de dose sur CBCT est attrayant dans une perspective de «rapporter» et… Show more

“…Scholars have tried various correction methods, [12][13][14][15] including deformable registration methods, 16,17 machine learning and deep learning methods. [18][19][20] Richter et al 21 found that the HU value of CBCT images (Elekta XVI system) directly correlated with the scanning conditions. For different tumor sites, appropriate correction strategies should be considered regarding the accuracy of CBCT-based dose calculations.…”
