Duration: 1 to 2 hours
Volumetric imaging has now become widely available for image-guided radiation therapy (IGRT), and gantry-mounted systems are poised to substantially alter radiation
therapy practice. This module will provide the learner a conceptual introduction to components of IGRT that need to be considered for transition of IGRT into practice – in particular, cone-beam computed tomography (CBCT). The ideal properties of targeting systems for image guidance will be explored, and an overview provided of the strengths and limitations of the image guidance tools currently available, with a focus on CBCT.
