摘要: Therapeutic ratio improvement by exploiting the highly conformal distributions that are enabled current image-guided radiation delivery systems depends on accurate identification and localization of both treatment targets healthy structures. While imaging is indispensable in accomplishing this task, reflection disease-related morphological functional features 3D 4D medical image datasets determined by: physical contrast generation mechanisms; system design, performance, capabilities; clinical acquisition protocols. The intent chapter to provide an overview above factors for most widely used modalities radiotherapy. Thus examines, varying degrees detail: Computed tomography (CT) Positron emission tomography-computed (PET/CT) Magnetic resonance (MRI)
