Abstract Purpose Sparing pharyngeal constrictor muscles (PCMs) during radiotherapy improves patient‐reported swallowing function. This study aimed to explore the feasibility of integrating knowledge‐based planning (KBP) with multicriteria optimization (MCO) in Eclipse v18.0 to selectively spare PCM, quantify the required trade‐off in prophylactic ...

Energy dependence of the GAFCHROMIC LD‐V1 in the diagnostic radiographic modalities
Abstract The GAFCHROMIC LD‐V1 radiochromic film is widely used in dosimetry because it can provide high‐resolution two‐dimensional dose distributions without processing. This study aimed to evaluate the response characteristics at different effective energies, from the low‐energy range of mammography to the high‐energy range of computed tomography. Net

AAPM medical physics practice guideline 13.a: HDR brachytherapy, part B
Abstract The goal of this report is to assist the clinical medical physicist in assuring that key quality standards and practice considerations are met to ensure safe, reliable, and reproducible high dose rate (HDR) brachytherapy (BT) treatment. This guideline has been developed to provide appropriate minimum standards for such services.
