{"title":"Enhancing patient understanding using visual aids in Head and Neck Education","authors":"Michelle Boey Ting Fang","doi":"10.1016/j.jmir.2025.102050","DOIUrl":"10.1016/j.jmir.2025.102050","url":null,"abstract":"<div><h3>Aim</h3><div>Head and Neck (HN) radiotherapy briefings are typically more time consuming compared to other sites due to the complexity of the treatment area. Information is often lost in translation, especially among elderly patients, who may misinterpret or lose focus. Conventionally, these briefings rely on verbal communication and checklist for the Radiation Therapists (RT), but this approach can lead to confusion and inefficiency. Visual aids help to overcome language barriers and medical jargons. Potentially they standardize briefing procedure, making it easier and quicker to convey information effectively. In this improvement project, we aim to find out the experience of the RTs on the effectiveness of educational slides in briefing patients on Day 1 and to gather suggestions for improving future patient education materials.</div></div><div><h3>Methods</h3><div>Educational slides with pictorial aids were designed to enhance the understanding and management of side effects for patients during their Day 1 briefing. Feedback on the content was gathered from HN Radiation Oncologist (RO) and the RTs working in the HN treatment room to ensure the content was clear and relevant. Slides were created using simple language and visuals based on the Common Terminology Criteria for Adverse Events (CTCAE) v4.0, which is an assessment tool used by our department HN ROs to evaluate radiation-induced toxicities. These slides were then tested at a clinical setting on HN radiotherapy patients. Survey was conducted via FormSG on 20 RTs who have utilised the slides in replacement of the briefing checklist.</div></div><div><h3>Results</h3><div>Interestingly, the results for the biggest challenge faced by the RTs during briefing were fairly equal, with a slightly higher percentage (35%) leaning towards ‘patients zoning out’ due to the overwhelming amount of information. All respondents (100%) agreed that the slides are beneficial as they are comprehensive and enhance patients' understanding more effectively than using a physical checklist alone. Additionally, 90% of respondents felt that the slides helped boost their confidence during briefings by reducing the likelihood of forgetting important information. However, 45% of respondents felt that the slides did not significantly reduce briefing times, possibly due to patient nervousness and the tendency of some patients to prompt more questions after viewing the educational slides.</div></div><div><h3>Conclusion</h3><div>The results showed that visual aids can significantly help RTs in delivering crucial information to HN RT patients. Moreover, the RTs felt it enhances patients’ understanding and retention of complex information during HN radiotherapy briefings. The project demonstrated the potential for further improvements, such as providing materials in multiple languages or offering physical samples of products. Future enhancements could include supplementary brochures and websites to support patients ","PeriodicalId":46420,"journal":{"name":"Journal of Medical Imaging and Radiation Sciences","volume":"56 2","pages":"Article 102050"},"PeriodicalIF":2.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144722659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional phantom-based studies, while valuable and eliminates concerns of radiation dose to participants, can lead to X-ray tube degradation due to the numerous exposures required for each parameter adjustment, thus increasing cost. In recent years, Monte Carlo simulation techniques have gained popularity among X-ray simulation studies. Among numerous Monte Carlo-based software for medical imaging, GATE (Geant4 Application for Tomographic Emission) has gained traction in medical imaging research. Released in 2004, the open-source software was dedicated to emission tomography research. However, newer models have allowed its application in CT simulations, and a few studies have since explored the use of GATE for CT research. Such studies performed only with the use of computer simulation, also known as in silico studies, offer several benefits. In silico studies do not require recruitment of participants, use of scanners, or Institutional Review Board (IRB) approvals, making them less expensive and faster. Moreover, there would not be ethical concerns about radiation risk and dose, and concerns about degradation of CT scanners, especially in the X-ray tubes. Therefore, the aim of this study is to explore the use of GATE, in investigating the effect of 1) low tube-voltage versus high tube-voltage protocols, 2) monoenergetic versus polyenergetic X-ray beams, 3) detector material, on image quality.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;A CT setup was modeled in GATE, based on a 25:1 scaled down model of a third generation rotate-rotate CT scanner, with a module 1 of the Gammex 464 ACR Phantom. All components of the GATE simulation design, including key parameters such as X-ray beam configuration, phantom design, and detector material, were configured with the use of macro files. Macro files in GATE are essentially text files that contain a sequence of commands. These commands instruct GATE on how to set up and run a simulation. Raw CT projection data was obtained from the simulations before image reconstruction was performed. Image reconstruction was performed using MATLAB version R2024a, involving four main steps: 1) Reading raw CT projection data, 2) Data rebinning, 3) Filtered back projection, 4) Converting data to DICOM image format for image analysis. Two data rebinning methods were used, the Feldkamp-Davis-Kress (FDK) method and the take method. ROIs in the material cylinders and the background were placed, for measurement of SNR and CNR to assess image quality. To evaluate differences in image quality, independent t-test was performed using MATLAB version R2024a.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;Our findings show variable effects in image quality, measured by SNR and CNR, across all three objectives.
