Leveraging deep learning-based segmentation and contours-driven deformable registration for dose accumulation in abdominal structures.
Frontiers in oncology(2022)
摘要
This study demonstrated a successful implementation of an automatic workflow for dose accumulation during liver cancer RT in a commercial TPS. The use of contour-driven DIR methods led to larger discrepancies between planned and accumulated doses in comparison to using an intensity only based DIR method, suggesting a better capability of these approaches in estimating complex deformations of the GI organs.
