- Organs at risk delineationPublication . Moura, Filipe Cidade de; Mast, MirjamDelineation of organs at risk and volumes of interest plays a crucial role in the radiation therapy chain. The process should be aligned with technological and clinical treatment approaches for optimal personalized care. Organs at risk contouring is part of the planning stage, after the initial simulation process, where volumetric CT imaging takes place to generate optimal 3D image set reconstruction for structure delineation and dose planning calculation. Relevant organs at risk for breast cancer radiation therapy have been described and contoured for global quality improvement and better communication between professionals. This chapter supports the evidence-based consensus from recently published literature, which served as the basis for the harmonization and standardization of practices in this planning radiation therapy stage. Electronic supplement material includes axial, sagittal, and coronal views of delineation on planning CT of relevant organs at risk.
- Simulation for breast cancerPublication . Mast, Mirjam; Moura, Filipe Cidade deOne of the important steps in radiation planning is the treatment simulation procedure. During this process, patient positioning, planning references, and the field of view are defined. Based on this CT scan the target volumes can be delineated. In this chapter we discuss key issues in the simulation procedure for breast cancer radiation planning.
