Purpose: A hybrid magnetic resonance linear accelerator (MRL) can perform magnetic resonance imaging (MRI) with high soft-tissue contrast to be used for online adaptive radiotherapy (oART). To obtain electron densities needed for the oART dose calcul

Organic plastic scintillators are attractive for several applications in medical dosimetry due to their high degree of water equivalence and their minimal perturbation of the radiation field. There is, however, a non-proportionality between the produ

In this work, a calorimetric system based on two graphite cores for absorbed dose measurements is described. The calorimeter also serves to correct the non-proportional (quenched) response in densely ionizing beams observed in scintillators. The syst

Purpose The IAEA protocol (TRS-398) for absorbed dose to water measurements in therapeutic MV photon beams, recommends that ionization chambers be calibrated directly in MV accelerator photon beams rather than in cobalt-60 combined with generic beam

Miniature organic plastic scintillators attached to optical fiber cables have found important uses in medical dosimetry, in particular for small-field dosimetry and field output factor measurements in megavoltage linear accelerator beams. Plastic sci

Purpose The purpose was to use organic plastic scintillators for determination of the beam quality correction factor ( k Q , Q 0 ) for flattening filters free (FFF) photon beams increasingly used in modern radiotherapy. The values were compared with
