Exradin W1 plastic scintillation detector for in vivo skin dosimetry in passive scattering proton therapy

In vivo dosimetry (IVD) is an important component of a comprehensive quality assurance program as a final check at the point of radiotherapy delivery; IVD can measure target doses, prevent dose delivery errors, and enhance the standard of patient care. IVD has been widely used in conventional external beam radiotherapy [1] and brachytherapy [2]. In external beam radiotherapy, IVD is mostly used for entrance dose measurement because it is easy to place a detector on the skin of the patient. For photon beam radiotherapy, transmission measurements using an electronic portal imaging device (EPID) are also gaining interest for IVD [3].
