Scintillators for 3D and 4D dosimetry: current status and future potential for clinical translation

摘要

New radiotherapy treatment techniques make unprecedented demands on dosimetry. Water equivalence, radiation hardness, high temporal and spatial resolution in 4D are no longer desirable but essential for safe implementation of several techniques. Plastic scintillation dosimetryhas the capabilities to meet all of the above criteria. Despite several attempts, a system has not yet been commercialised for widespread availability in the clinic. Successful translation of good science to the benefits of clinical practice demands that the primary focus be shifted from the technological innovation to the patient needs. We will present the clinically beneficial features of scintillation dosimetry and some remaining challenges. Then we will discuss the barriers to widespread availability of scintillation dosimeters.
