Fluorescent nuclear track detectors as a tool for ion-beam therapy research

Fluorescent nuclear track detectors based on Al2O3:C,Mg with their excellent efficiency for detection of heavy charged particles and full 3D information from laser scanning microscopy allow a multitude of issues related to ion-beam cancer therapy to be tackled. A recently established read out protocol enables the utilization of a commercial microscope similar to those available in many life-science environments. This contribution illustrates the approach, its potential and limitations, as well as applications in clinical ion beams.

► Fluorescent nuclear track detectors (FNTDs) are based on alumina. ► They represent a unique research tool for ion beam cancer therapy. ► We present a protocol for FNTD read out using a commercial laser scanning microscope.
