3D transformer-based dose prediction in HDR brachytherapy for cervical cancer

BMC Cancer
Background The clinical process of high-dose-rate brachytherapy (HDRBT) is time-consuming and relies on user expertise and preference. Deep learning-based dose prediction can act as a quality assurance (QA) tool to identify suboptimal needle placement ...

Treatment of hepatocellular carcinoma with gluteus medius metastasis: a case report and a literature review

Frontiers in Oncology
Hepatocellular carcinoma (HCC) accounts for 85%–90% of all primary liver cancers (PLCs). Owing to the occult nature of HCC, most patients present at an advanced stage at the time of initial diagnosis and have a poor prognosis.

Quantitative Cherenkov‐excited fluorescence emission dosimetry for HDR Co‐60 brachytherapy: Calibration and planar validation against TPS

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Accurate dose verification in High‐Dose‐Rate (HDR) brachytherapy presents a significant challenge due to steep dose gradients and the absence of beam collimation. Conventional quality assurance (QA) methods typically rely on point detectors or film‐based techniques, which lack the capability to provide real‐time, full‐field ...

Preclinical feasibility of EPID‐based transit dosimetry for total body irradiation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Conventional extended‐distance total body irradiation (TBI) is commonly verified using point dosimeters, which provide limited spatial information and require additional handling during a prolonged treatment procedure. A portable charge‐coupled device (CCD)‐based electronic portal imaging device (EPID) positioned downstream of the ...

A centralized hybrid model for regulatory inspection readiness in a multi‐site radiation oncology system

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background State regulatory inspections of radiation‐producing treatment equipment combine a review of quality assurance and regulatory records with direct verification of facility and safety systems. When these activities are performed entirely on‐site across multiple facilities, real‐time document retrieval can prolong visits and divert ...

Routine physics work efficacy and efficiency improvement through a shared‐duty physicist‐of‐the‐day model in a multi‐hospital radiation oncology network

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Large multi‐hospital radiation oncology networks often rely on site‐exclusive physicist coverage models that can lead to imbalanced workload distribution, inconsistent task execution, communication fragmentation, and vulnerability to delayed or missed quality checks.
