On Friday 12 November at 14:00, Erik Buch Jørgensen defends his dissertation entitled "In vivo dosimetry based source tracking and 3D dose reconstruction for treatment verification in afterloading brachytherapy".
Brachytherapy is a cancer treatment where small radioactive sources are inserted into the patient to irradiate the tumour. This gives a highly localised delivery of the dose which effectivly spares the normal tissue around the tumour. However, there is a potential to improve the treatment even further: The existing equipment to monitor that the delivered dose is equal to the planned dose is imprecise and the information cannot be delivered fast enough for the clinical personal to react on it. In a new ph.d.-project a technology is applied to solve this problem: time-resolved real-time scintillator based dosimetry.
During this project it was shown how this new technology can be used to accuratly determine whether the radioactive source is correctly placed inside the patient. The consequences of observed deviations in source positions were investigate by calculating the dose administered to the tumour and organs at risk. Furthermore, a new dosimetry system was characterised and implemented in the clinic.
The summary is written by the PhD student.
The defence is public and takes place in auditorium C114-101, Aarhus University Hospital, Palle Juul-Jensens Boulevard 99, entrance C, level 1, 8200 Aarhus N and online via Zoom. Please read full press release for more information.
