    S. Salvatori1,2 and S. Pettinato1,2 Radiation therapy is now widely applied for cancer care. For an effective and safe treatment, accurate dosimetry is mandatory. The evolution and widespread adoption of modern dynamic and conformal radiotherapy techniques have imposed several challenges from a dosimetric perspective. Commonly employed radiation beams include high-energy (6–18 MeV) photons or electron beams for external treatments, as well as low-energy (tens of…

    S. Pettinato1,2; M. Girolami2; S. Salvatori1,2; M. C. Rossi3 and D. Barettin1 FLASH radiotherapy is an emerging technique that uses high dose rates (~40 Gy/s) and high dose-per-pulse values (~1 Gy/pulse) by delivering the total dose in a single session, resulting in significantly shorter treatment times and safeguarding healthy tissues. In this field, single-pulse dose measurements appear…

    S. Pettinato1,2; M. Girolami2; S. Salvatori1,2; R. Olivieri; A. Stravato and C. Caruso The widespread diffusion of precision radiotherapy techniques, geared toward the release of larger dose gradients in shorter time frames, is leading to new challenges in dosimetry. Accurate dose measurements are essential to check for beam anomalies and inaccuracies to ensure treatment efficacy…

    Electron beams generated by linear accelerators (LINACs) used in FLASH radiotherapy consist of microsecond pulses and are therefore characterized by instantaneous dose rates on the order of MGy/s. Diamond represents one ofthe most promising materials for fabricating reliable dosimeters for FLASH radiotherapy. So far, excellent results have been achieved using detectors based on high-quality single-crystal…
