Summary/Conclusion

Functional Image based RT target volume delineation • Improves accuracy of contouring • Gives robust volumes PET-based contouring • Different automatic contouring methods available • Large differences in complexity but also in accuracy and robustness • Validation is crucial Multi-modality imaging for contouring • May again improve target volume delineation • Validation is difficult • Potential for functional imaging based therapy adaptation Image-based delineation of radioresistant tumor sub- volumes • Eg. Hypoxia PET, Diffusion MRI, …
