Outlook – the IntraDose project
Development towards a preclinical prototype:
- lightweight and highly mobile with vast workspace,
- broader energy range (4 – 12 MeV),
- Intuitive & safe „augmented” applicator docking with user selectable docking scheme (soft- or hard-docking),
- 3 – 12 cm circular applicators (other shapes possible; no bevel),
- user friendly control system,
- planning software.
Ready for certification early 2016.
