SU‐GG‐T‐49: Real Time Dose Verification for Novel Shielded Balloon Brachytherapy

Purpose: The validation of a novel approach for reducing skin doses to an acceptable level during Accelerated Partial Breast Irradiation (APBI) when the balloon‐to‐skin distance is inadequate (less than 7 mm) is reported. The study uses a real time dose verification method for a metallic shielded ba...

Description
Summary:Purpose: The validation of a novel approach for reducing skin doses to an acceptable level during Accelerated Partial Breast Irradiation (APBI) when the balloon‐to‐skin distance is inadequate (less than 7 mm) is reported. The study uses a real time dose verification method for a metallic shielded balloon applicator using scintillation fiber technology. Method and Materials: Partial shielding of the radiation dose to the skin using iron or other ferrous powder could enable the extension of APBI to some patients. With small external and pre‐determined magnetic fields (
