“Patient-specific validation of deformable image registration in radiation therapy: Overview and caveats”

Over the last few decades, deformable image registration (DIR) has gained popularity in image‐guided radiation therapy for a number of applications, such as contour propagation, dose warping, and accumulation. Although this raises promising perspectives for the improvement of treatment outcomes and quality of radiotherapy clinical practice, the variety of proposed DIR algorithms, combined with the lack of an effective quantitative quality...
