ESTRO meets Asia 2024

Consistent, lower cost learning opportunities are simply enabled via the platform of a mobile phone. The supporting xAPI application has built in quality assurance and reporting functions, that would support international collaboration and evaluation or comparison, with minimal overheads. Approaches to learning could range from individual-based assessment with formal or informal objectives, to the testing of knowledge in support of mentoring processes or peer review. Learning experiences can be served up regularly (pushed) or accessed (pulled) on demand. The application also automatically supports micro-credentialling, that is, recognising learning on a small scale, including the automatic issue of certificates to participants for agreed sets of learning. In environments where medical physicists are responsible for their own professional development, the ability to demonstrate that standards have been met, or knowledge gained, for broader certification or other purposes, may or may not be useful.

The technology used in the Australian/NZ project is an application called Forget Me Not.

New radiobiological insights and how we can apply them in the clinic

Abstract

The title of this talk is a challenge. Clinical application outside a controlled trial should be rooted in solid evidence and many "new radiobiological insights" are just that - new.

We will navigate the not-so-new landscape of normal tissue tolerance information and discuss the road from the seminal QUANTEC papers (Quantitative Normal Tissue Effects in the Clinic) to the now recently published PENTEC papers (Pediatric Normal Tissue Effects in the Clinic). These efforts serve as a good bases for discussing how to perform the best possible dose plan optimization in your daily clinic. But they also serve to discuss the limitations of our current approaches and how to move beyond those limitations in the normal tissue sparing efforts. But we also need to consider the target. It is now more than 20 years ago C. Ling published the idea of image based dose painting to a biological target volume with S. Bentzen proposing to extend this concept to a dose painting by umbers setting. Why has it not entered the clinic? Or has it indirectly? We will discuss target dose distributions, altered fractionations and inhomogeneous dose distributions and how to move beyond the current state - in routine clinic and in research.
