[en] In modern conformal radiotherapy, a more precise delivery of a higher dose to the tumor while sparing the healthy tissues is aimed. The implementation of these new treatment techniques requires advanced imaging and dosimetry to guarantee patient safety. In this study, we investigated the dosimetric response of Al203:C optically stimulated luminescence droplets that can be used as online dosimeters. The dosimeters are composed of microparticles of Al2O3:C with diameters ranging from 5 μm to 35 μm, and which are mixed with a photo-curable polymer. Drops of dosimetric compound, of 1 μl in volume (1 mg of powder per ml of polymer) with a diameter of about 2 mm, were fabricated. (authors)
