A simple method to back-project isocenter dose of radiotherapy treatments using EPID transit dosimetry

Brazilian Journal of Radiation Sciences, 2017
The aim of this work was to implement a simple algorithm to evaluate isocenter dose in a phantom using the back-projected transmitted dose acquired using an Electronic Portal Imaging Device (EPID) available in a Varian Trilogy accelerator with two ...

Demonstrating the use of population level data to investigate trends in the rate, radiation dose and cost of Computed Tomography across clinical groups: Are there any areas of concern?

Journal of Medical Radiation Sciences, EarlyView.
This repeated cross‐sectional study examined trends in CT use, costs and associated radiation dosages between high‐level clinical groups. CT use increased for most patient groups though the degree of increase varied between groups, while trends in costs and radiation dosages varied substantially between clinical groups. This work highlights areas which

Size‐specific dose estimates calculated using patient size measurements from scanned projection radiograph in high‐resolution chest computed tomography

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 85-92, March 2025.
This study established that patient's lateral width measurements made from scanned projection radiograph (SPR) is an overestimate compared to those measured from tomographic slices by about 10%. Size‐specific dose estimates (SSDE) calculated using lateral width measured from SPR correlates well with SSDE calculated using water equivalent diameter of ...

Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

Molecular theranostics: principles, challenges and controversies

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 156-164, March 2025.
Molecular theranostics offers a powerful tool to drive precision medicine in nuclear oncology. While theranostics is not a new principle in nuclear medicine, recent advances in instrumentation and radiopharmacy have driven a reinvigoration and a broader suite of applications.

Artificial intelligence in radiation therapy treatment planning: A discrete choice experiment

Journal of Medical Radiation Sciences, EarlyView.
We conducted a discrete choice experiment (DCE) to explore the preferences of radiation oncology professionals regarding which key features of AI systems might impact future adoption in clinical settings. Our findings suggest that the respondents preferred AI systems that offer the largest time saving, and that provide explanations of the AI reasoning (

Technique considerations for implementing volumetric‐modulated arc therapy for total body irradiation within an Australian tertiary institution

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 ...

Comparative Effectiveness of Immersive Virtual Reality and Traditional Didactic Training on Radiation Safety in Medical Professionals: A Crossover Study

Journal of Medical Radiation Sciences, EarlyView.
This study evaluates the comparative effectiveness of immersive virtual reality (VR) training and traditional didactic training on radiation safety among medical professionals, with a focus on reducing radiation exposure. A 2‐year randomised crossover trial involving 39 participants from cardiac catheterisation labs and orthopaedic theatres was ...

Local Diagnostic Reference Levels in Digital Breast Tomosynthesis

Journal of Medical Radiation Sciences, EarlyView.
Diagnostic Reference Levels (DRLs) are a guideline to indicate whether the radiation administered during medical procedures performed under routine conditions is unusually high or low. There are currently no national DRLs in Australia for Digital Breast Tomosynthesis Mammography.

Estimation the Maximum Tolerance Activity of Blood by a Simple Algorithm Method in Pediatric Differentiated Thyroid Cancer Patients Treated With Empirical Radioactive Iodine Dosing Based on Risk Stratification

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT After total thyroidectomy for pediatric differentiated thyroid cancer (DTC), the subsequent radioactive iodine (RAI) treatment is a robust therapy, the dosing of which is a major concern. This study was designed to evaluate the “as high as safe administration” (AHASA) principle of RAI treatment in pediatric DTC patients based on the maximum ...
