Article Synopsis
- This study investigates the effects of 3D-printed stainless steel samples on dose delivery in gynecologic brachytherapy, particularly in the presence of an Iridium-192 source intended to spare critical organs.
- Experimental setups involved positioning the samples at different distances from a radiation source and measuring the radiation dose using specialized film.
- Results indicated that the steel samples reduced radiation dose compared to solid water and suggested these materials could be used in personalized applicators to enhance patient safety during treatment.

Department of Radiation Oncology, QE2 Cancer Centre, Nova Scotia Health, Halifax, Canada; Departments of Radiation Oncology.
Purpose: The goal of this study was to evaluate the image quality provided by a novel cone beam computed tomography (CBCT) platform (HyperSight, Varian Medical Systems), a platform with enhanced reconstruction algorithms as well as rapid acquisition times. Image quality was compared with both status quo CBCT for image guidance, and to fan beam CT (FBCT) acquired on a CT simulator (CTsim).
Methods And Materials: In a clinical study, 30 individuals were recruited for whom either deep inspiration (DIBH) or deep exhalation breath hold (DEBH) was used during imaging and radiation treatment of tumors involving liver, lung, breast, abdomen, chest wall, and pancreatic sites.
