Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 165-172, March 2025.In 2020, our institution transitioned to the Eclipse™ treatment planning system and to Truebeam® linear accelerators with 6 MV and 10 MV energies. The linear accelerators were installed in smaller bunkers that could not accommodate 400 cm FAD. A multidisciplinary team within the institution was created to evaluate existing total body irradiation ...

Boost Approaches in Patients Undergoing Postoperative Radiotherapy
Journal of Surgical Oncology, EarlyView.ABSTRACT The use of breast conservation surgery for early‐stage breast cancer is common, and adjuvant radiotherapy is often recommended to reduce the risk of ipsilateral breast tumor recurrence. Historical trials have used sequential boost techniques with favorable outcomes with reduction in local recurrence and acceptable cosmetic outcomes.

Quantifying uncertainty in calibration and clinical application of EBT-4 Gafchromic film dosimetry. [PDF]
Med PhysAbstract Background GAFchromic films (GAFs) are essential tools in radiotherapy dosimetry, but uncertainties in calibration methods limit their accuracy and hinder consistency across clinical practice. Purpose This study aimed to perform a comparative analysis of different calibration functions for GAFchromic EBT4 films in single‐ and double‐channel ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Numerical simulations can be adopted to aid the evaluation of the interaction between switched gradient fields and metallic implants and estimate the possible temperature increase. Anyway, an analysis of the consistency of their prediction with experiments is lacking, differently from what can be found for exposure to radiofrequency ...
