Material development: Optically-stimulated luminescence (OSL) is the main focus of our material development efforts. Implementation of OSL particles in the dosimeters will allow for reusability and a safer workflow.
Read-out techniques: In order to read out the OSL dosimeters, a new optical technique has to be developed. When reading out the dosimeters we want as large a signal as possible and also a method to “bleach” the dosimeter afterwards, so it is ready for the next use.
Magnetic resonance guided radiotherapy: Magnetic resonance imaging (MRI) and radiotherapy have been fusioned to create MRI-guided radiotherapy. The dosimeters developed in our group are meant to help investigate the effects of radiotherapy treatments in the presence of a magnetic field.
Influence of motion and deformation:.Organs and tumors are subject to deformation during treatment due to respiration, circulation, peristalsis etc. and the deformable silicone-based dosimeters opens a realm for investigating how the dose deposition is affected when the irradiated material is deformed.
Clinical integration: These dosimeters can be cast into anthropomorphic shapes, which would make them ideal to use for patient specific quality assurance. To make a real impact this requires the dosimeters to be easy to use and not too time-consuming.
