Multi-planner validation of RapidPlan knowledge-based model for volumetric modulated arc therapy in prostate cancer.

Purpose: To investigate the performance of a model-based optimization process for volumetric modulated arc therapy (VMAT) applied to prostate cancer patients with the multi-planner.

Methods And Materials: The 120 prostate plans for VMAT treatment were entered into the database system of the RapidPlan (RP) knowledge-based treatment planning. The treatment planning data for each plan was used to create and train the RP model.

Estimated radiation doses to ovarian and uterine organs in breast cancer irradiation using radio-photoluminescent glass dosimeters (RPLDs).

Introduction: The well-being of breast cancer patients is essential, especially fertility in patients of reproductive age. The objective of this study was to estimate the radiation doses to the ovaries and uterus for different treatment techniques of breast cancer irradiation using radio-photoluminescent glass dosimeters (RPLDs).

Methods: A Farmer-type ionisation chamber (IBA FC-65G) and RPLDs were used to measure in- and out-of-field radiation doses in a solid water phantom.
