This study evaluated the current views and opinions of Radiation Therapists (RTs) in British Columbia relating to how COVID-19 P&amp;P changes have impacted their clinical practice.

When asked to rank the factors that most impacted RT practice, RTs identified increased PPE usage (83 %), absence of volunteers (74 %), and room occupancy limits (70 %) as the leading P&amp;P changes that negatively impacted their practice; while plexiglass barriers (39 %), re-arranged workspaces (37 %) and working remotely (12 %) were the least negatively impactful.</p></div><div><h3>Conclusion</h3><p>The majority of RTs across BC Cancer responding to the questionnaire indicated that their ability to provide patient care and their staff-work environment were negatively impacted by implemented COVID-19 P&amp;Ps.

It examines the current legislative framework, assesses the trust and reliability of AI tools, and proposes future directions for ethical AI integration in radiography. AI systems significantly enhance diagnostic radiography by improving diagnostic accuracy and efficiency in stroke detection, brain imaging, and chest reporting. However, AI raises substantial ethical concerns due to its 'black-box' nature and potential biases in training data. The Therapeutic Goods Administration's reforms in Australia, though comprehensive, fall short of fully addressing issues related to the trustworthiness and legal liabilities of AI tools. Adopting a comprehensive research strategy that includes doctrinal, comparative, and public policy analyses will facilitate an understanding of international practices, particularly from countries with similar legal systems, and help guide Australia in refining its regulatory framework. For an ethical future in radiography, a robust, multi-disciplinary approach is required to prioritize patient safety, data privacy, and equitable AI use. A framework that balances technological innovation with ethical and legal integrity is essential for advancing healthcare while preserving trust and transparency. Healthcare professionals, policymakers, and AI developers must collaborate to establish a resilient, equitable, and transparent healthcare system. Future research should focus on multi-disciplinary methodologies, combining doctrinal, comparative, and public policy research to provide comprehensive insights.
