# Design optimization of novel inorganic scintillation detectors for the small animal radiation research platform (SARRP)

Preclinical trials involving mice are now a standard component of research in radiation oncology and radiobiology. Image-guided irradiations of small animals utilize small field sizes ($⩽$1 × 1 cm2), necessitating accurate and precise real-time dosimeters with high spatial resolution capabilities for treatment verification and quality assurance [1]. Plastic scintillation detectors (PSDs) are commonly used in optical fibre-based dosimetry in this field due to the small geometry and near water-equivalence of the active volume. However, the low signal output of these detectors can lead to uncertainties which affect the precision of low dose measurements and thus dosimetric QA.
