Transformer models show mixed robustness in radiation therapy planning

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a transformer-based pipeline for predicting fluence maps in radiation therapy, aiming to speed up treatment planning. Their study evaluated the model's robustness against various clinically realistic perturbations, including geometric shifts, noise, and domain changes. The findings indicated that while the model degrades smoothly under moderate disturbances, it fails sharply with severe rotations and noise, with hierarchical transformers showing better resilience.

    Robustness of Transformer-Based Fluence Map Prediction Under Clinically Realistic Perturbations

    arXiv:2605.00904v1 Announce Type: new Abstract: Learning-based fluence map prediction offers a fast alternative to iterative inverse planning in intensity-modulated radiation therapy (IMRT), but its robustness under realistic distribution shifts remains unclear. We study a two-st…
