Prone Breast Radiotherapy on the MR‐Linac: A Technical Note on Skin‐Couch Contact Dose Effects

Journal of Medical Radiation Sciences, EarlyView.
This retrospective planning study evaluated the dosimetric effects of skin‐couch contact during prone APBI on a 1.5 T MR‐Linac by comparing treatment plans calculated with and without a magnetic field. While the presence of the magnetic field increased overall superficial skin dose, it consistently reduced dose at the skin‐couch contact region ...

StrataXRT Versus Mepitel Film for Prevention of Acute Radiation Dermatitis in Postmastectomy Radiotherapy: A Pooled Analysis of Intra‐Patient Randomised Trials

Journal of Medical Radiation Sciences, EarlyView.
In 120 patients receiving postmastectomy radiotherapy, each irradiated chest wall was divided into medial and lateral halves, which were randomised to Mepitel Film or StrataXRT. Mepitel Film reduced grade 2–3 acute radiation dermatitis and clinician‐assessed erythema and moist desquamation over time.

Dosimetric Outcomes of Definitive Radiation Therapy to Anal Squamous Cell Carcinoma in a Single Institution Using Volumetric Modulated Arc Therapy Evaluated Against Australian and International Treatment Planning Guidelines

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated 43 clinically approved VMAT plans for anal squamous cell carcinoma (SCC) against RTOG, eviQ, ANROTAT and departmental planning guidelines to assess the achievability of current dose constraints. While most target coverage and median OAR dose objectives were within protocol, not all constraints were consistently met, supporting the ...

Deep Learning and Machine Learning Algorithms for Cervical Cancer Segmentation on MRI: A Systematic Review

Journal of Medical Radiation Sciences, EarlyView.
This systematic review summarizes current evidence on machine and deep learning algorithms for MRI‐based cervical cancer segmentation, demonstrating promising diagnostic performance and potential for workflow automation. However, methodological heterogeneity, limited external validation, and low certainty of evidence highlight the need for standardized

Daytime Idle Energy Reduction in Radiotherapy Simulation Computed Tomography: A Prospective Workflow‐Based Evaluation

Journal of Medical Radiation Sciences, EarlyView.
Radiotherapy simulation CT includes prolonged, procedure‐dependent non‐acquisition periods associated with treatment preparation and immobilisation. Built‐in power‐saving operation shifted idle power demand to a lower‐power state and reduced daytime energy consumption by 5.8% without meaningful workflow disruption. Generative AI was used to create some
