“…Comparing the measured gel signal with the dose distribution for a monoenergetic 135 MeV/u carbon ion Bragg-peak exhibited deviations of less than 8% in front of the Bragg peak and up to 15% beyond. This radio-fluorogenic gel has been further characterized and the response was found to be LET-independent up to 8000 keV μmm −1 and linearly dependent on dose (Maeyama et al 2024). The fluorescence readout, however, was performed with a 2D flatbed scanner, and 3D readout of larger volumes as required for clinical application has not yet been established.…”

Modern radiotherapy delivers highly conformal dose distributions to irregularly shaped target volumes while sparing the surrounding normal tissue. Due to the complex planning and delivery techniques, dose verification and validation of the whole treatment workflow by end-to-end tests became much more important and polymer gel dosimeters are one of the few possibilities to capture the delivered dose distribution in 3D. The basic principles and formulations of gel dosimetry and its evaluation methods are described and the available studies validating device-specific geometrical parameters as well as the dose delivery by advanced radiotherapy techniques, such as 3D-CRT/IMRT and SRS treatments, the treatment of moving targets, online-adaptive MRgRT as well as proton and ion beam treatments, are reviewed. The present status and limitations as well as future challenges of polymer gel dosimetry for the validation of complex radiotherapy techniques are discussed.
