Deformable Dose Mapping and Accumulation Techniques for Stereotactic Body Radiotherapie (SBRT) of Longkankers

Deformable dose mapping and accumulation are essential tools in lung cancer stereotactic body radiation therapy (SBRT). Here, we provide a critical review of deformable image registration (DIR)–based dose mapping and accumulation techniques in SBRT for lung cancers, with emphasis on methodological principles, clinical applications, limitations, and guidance for practice. A broad appraisal of the literature was conducted, emphasizing DIR algorithms and related dose mapping strategies, including direct dose mapping, voxel warping, and energy/mass-congruent mapping.
