Question

Accepted Answer

Medical Physicists' Evolving Role in Ensuring AI Safety in Healthcare

Medical physicists are uniquely positioned to bridge the gap from traditional machine quality assurance (QA) to the oversight of artificial intelligence (AI) systems in healthcare. Their established expertise in validating the safety and accuracy of medical equipment, coupled with their skills in risk assessment and quality assurance, are directly transferable to the complex domain of AI. As AI becomes more integrated into clinical practice, medical physicists can extend their responsibilities to encompass the continuous monitoring and validation of AI algorithms, thereby ensuring these systems remain reliable, fair, and trustworthy for patient care.
Transferable Expertise in Validation and Quality Assurance

Medical physicists have a long-standing role in ensuring the safe and accurate operation of complex medical technologies such as CT scanners, MRI systems, and radiotherapy equipment. This involves rigorous validation processes, ongoing performance evaluations, and comprehensive quality assurance protocols to guarantee that these machines function as intended and pose minimal risk to patients. Their established methodologies for testing equipment, managing risks, and ensuring clinical technology performs reliably are directly applicable to the oversight of AI systems, which also require robust validation and continuous quality management.
Addressing AI-Specific Challenges in Clinical Settings

The introduction of AI into healthcare presents unique challenges that medical physicists are well-equipped to address. Unlike conventional equipment that generally maintains consistent performance after commissioning, AI systems can evolve due to software updates, new datasets, and changing patient populations. Medical physicists can apply their critical thinking skills to assess whether AI tools developed in different geographical or demographic contexts, such as those trained on European or North American data, will perform equally well for Malaysian patients in cities like Kuala Lumpur or rural areas. They can investigate potential biases and ensure equitable performance across diverse patient groups.
Expanding Responsibilities in AI Governance and Monitoring

As AI's role in healthcare expands, the responsibilities of medical physicists are evolving to include the oversight of algorithms and AI-driven systems. Future roles may involve actively monitoring the performance of AI tools in real-world clinical settings, identifying and mitigating potential biases that could affect patient care, and contributing to cybersecurity efforts to protect sensitive patient data processed by these systems. Their involvement in hospital AI governance committees will be crucial for establishing frameworks that ensure AI remains accurate, reliable, and fair throughout its lifecycle.
Building Patient Trust Through Continuous Oversight

The ultimate goal of medical physicists' expanded role in AI oversight is to build and maintain patient trust in AI-enabled healthcare. By applying their expertise to ensure that AI systems are properly tested in local environments, perform consistently across different patient demographics, and retain their accuracy after software updates, they provide a critical layer of assurance. This continuous oversight is essential for demonstrating that healthcare innovation, even with advanced AI, remains centred on patient welfare, safety, and effectiveness, thereby safeguarding the integrity of digital transformation in Malaysian healthcare.
