Medical luminescence dosimetry

The ionizing radiation dosimetry section at DTU Health Tech develops special luminescence dosimetry systems aimed at applications within the field of medical physics. Our main method is based on organic plastic scintillators or aluminium oxide crystals attached to optical fiber cables. These point detectors are well suited for time-resolved in vivo measurements, for example, during brachytherapy of cervical cancer patients. The plastic scintillator detector systems are mainly used for output factor measurements in small MV fields.

The optical fibers have a diameter of 1 mm and special adapters have been developed for positioning the probes.
