ABSTRACT
Since their first application to radiation therapy dose measurements, plastic scintillation detectors (PSDs) have been mainly used as single-point detectors. They are well suited for dosimetry in radiation therapy because of their typically high spatial resolution. Applications to radiosurgery and intensity-modulated radiation therapy are good examples (Klein et al. 2010, 2012; Morin et al. 2013). Nevertheless, physicists must often measure complex spatial distributions. As a result, other detectors such as ion chambers and diodes are available in arrays. PSDs also exist in arrays (Guillot et al. 2011a, 2013; Gagnon et al. 2012) but can be cumbersome and delicate to use.
