Evaluation of radiochromic formulations for dosimetry in high-energy photon and proton beams.

ABSTRACT: Radiochromic crystals have many suitable features for dosimetry across a broad range of radiotherapy modalities, yet the study of these materials within the medical physics community has been limited. Here, we study three types of radiochromic pentacosa-10,12-diynoic acid-based formulations: two analogues of commercially available materials and one newly developed. Formulations coated on polyethylene are irradiated with photon (6 and 10 MV) and proton (74 MeV) beams (0-25 Gy) using custom fibre-optic setups that enable real-time transmission measurements at 1.5-2 cm depth to maintain dosimetric accuracy. The dose response to ionizing radiation is compared between the formulations and all formulations were characterized using a variety of analytical methods. The response of radiochromic cry
