Description
We are pleased to announce that the 14th edition of the International Conference on 3D Dosimetry (IC3DDose) will be held for the first time in France, in the city of Caen, from 15 to 17 June 2026.
Caen is a dynamic place for medical physics and radiation research, hosting leading institutions such as the Grand Accélérateur National d’Ions Lourds (GANIL), the Laboratoire de Physique Corpusculaire (LPC), the François Baclesse Cancer Center, and the CyclHad hadrontherapy center. Scheduled shortly after PTCOG 2026, which takes place nearby, IC3DDose 2026 offers a unique opportunity for cross-disciplinary interactions between the particle therapy and dosimetry communities.
Following the tradition of previous editions, the conference will bring together an international community of scientists and clinicians working at the forefront of three-dimensional and four-dimensional radiation dosimetry. Attendance will be limited to 90 participants to foster lively discussions and close interactions, combining scientific talks, poster sessions, and informal networking during coffee breaks.
The tentative topics for the IC3Ddose 2026 are:
- New materials and readout methods for advanced and 3D dosimetry
- 3D (and 4D) dosimetry – basics and new developments
- Novel dosimetry for the clinic today and for the emerging irradiation modalities of tomorrow (small field, MR-linac, protons, flash, grid therapy…)
- Clinical dosimetry applications (evaluation of motion and deformation, quality assurance (QA) and end-to-end)
- Linear Energy Transfer (LET) mapping
- Real-time 3D dose imaging including scintillation and Cherenkov
- Optically-stimulated-luminescence (OSL) based 3D dosimetry
- 3D dose reconstruction, modeling, and data evaluation including artificial-intelligence (AI) approaches
