Parallel 2A - EM physics validation for medical use
- Key experimental and theoretical medical physics benchmarks (see also session 4A).
- Are the simulations getting better or worse in terms of accuracy and speed? Should we be working to improve the level of agreement between the experiment and simulation? Should we be working to improve the speed of the simulation?
- Acceptability of the experimental benchmarks that have been identified and the tolerance(s) recommended for each benchmark.
- Consideration of additional benchmarks.
