Image guided high-dose-rate brachytherapy versus volumetric modulated arc therapy for head and neck cancer: A comparative analysis of dosimetry for target volume and organs at risk

Radiology and Oncology, 2018
The aim of the study was to present dosimetric comparison of image guided high-dose-rate brachytherapy (IGBT) with volumetric modulated arc therapy (VMAT) for head and neck cancer regarding conformity of dose distribution to planning target volume (PTV ...

Association of recurrence patterns and outcome with HR and HER2 status in patients with resected brain metastases from breast cancer

International Journal of Cancer, Volume 159, Issue 2, Page 440-449, 15 July 2026.
What's new? While treatment strategies for solid brain metastases have been relatively uniform across cancer subtypes, tailored approaches are warranted. In this observational study, intracranial recurrences after microsurgical resection occurred significantly earlier and more frequently at distant sites in patients with triple‐negative breast cancer ...

Latent density discrepancies in commercial lung‐equivalent inserts and their clinical dosimetric impact

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Accurate heterogeneity correction in high‐precision radiotherapy relies on precise computed tomography (CT) number‐to‐density conversion via the Hounsfield unit look‐up table (HLUT). While physical properties of tissue‐equivalent materials are generally assumed consistent with manufacturer specifications, an independent audit ...

Dual‐scan conformal cone‐beam CT for targeted image‐quality improvement using dynamic collimation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is routinely used for image guidance in radiation therapy, but conventional full‐field CBCT acquisition may expose anatomically irrelevant regions and generate substantial scatter, which degrades soft‐tissue contrast and limits the accuracy of target localization and adaptive radiotherapy ...

Synthetic CT‐enabled weekly adaptive radiotherapy for nasopharyngeal carcinoma: Optimizing plan adaptation triggers through volumetric–dosimetric monitoring

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background and purpose Anatomical changes during radiotherapy for nasopharyngeal carcinoma (NPC) frequently compromise target volume coverage while escalating dose delivery to organs at risk (OARs). In adaptive radiotherapy (ART), optimizing workflow efficiency to minimize clinical workload while maximizing patient benefit remains a ...
