Ninjaflex vs Superflab: A comparison of dosimetric properties conformity to the skin surface Planning Target Volume coverage and positional reproducibility for external beam radiotherapy

摘要

When planning and delivering radiotherapy, ideally bolus should be in direct contact with the skin surface. Varying air gaps between the skin surface and bolus material can result in discrepancies between the intended and delivered dose. This study assessed a three‐dimensional (3D) printed flexible bolus to determine whether it could improve conformity to the skin surface, reduce air gaps, and improve planning target volume coverage, compared to a commercial bolus material, Superflab.
