From: A prospective comparison of adaptive and fixed boost plans in radiotherapy for glioblastoma
A CT and MRI procedures for ART. The fixed boost plan and adaptive boost plan are created on CTpre and CTmid, respectively. The dose distributions of PTVpost (PTV created by MRIpost) in the fixed boost plan and adaptive boost plan are compared by fusing MRIpost to CTpre and CTmid. B MRI with three timings (Pre, Mid, Post) and two boost plans. C Left: GTV-post (red) and PTVboost-post (magenta) on the CTpre (fixed boost plan). Right: GTV-post (red) and PTVboost-post (magenta) on the CTmid (adaptive boost plan). ART, adaptive radiation therapy; CT, compute tomography; GTV, gross target volume; MRI, magnetic resonance imaging; PTV, planning target volume
