MSF – Medical Radiation Physics
- Medical Radiation Physics is a vast and complex translational research topic that deals with
radiation physics applied to medicine and biology for medical radiation imaging and radiation therapy - possible collaboration across Fysikum - or beyond Fysikum Radiation Sources Detectors Dosimetry Radiation Biology Radiation Interaction Diagnostic Radiology Radiation Therapy Radiation Protection Nuclear Medicine
MSF - Possible Supervisors at Fysikum
- Potential BSc supervisors at Fysikum, e.g.:
○ Bo Sundborg ○ Michael Odelius ○ Mark Stockett ○ Tony Hansson ○ Henrik Öström ○ Samuel Silverstein ○ Fredrik Hellberg ○ Alfredo Ferella ○ …
BSc projects topics may involve:
- any kinds of radiation interaction
- aspects of dosimetry or quantifying radiation fields
- accelerator physics
- interdisciplinary physics topics involving
chemistry and/or biology
- detectors
- image analysis
- ...

Research at MSF
- Radiotherapy
- the use of ionising radiation in the
management of malign and benign diseases
- Radioprotection
- assessing and minimising the risk of stochastic
detrimental effects of radiation such as induction of cancer after medical radiation exposures
- improving preparedness and competence in
Sweden to cope with nuclear emergencies

Treatment outcome modelling
Customised RT based on functional imaging
MSF – Proton Therapy
➢ Proton treatment planning comparison to photon therapy ➢ Proton treatment evaluation and
- ptimisation
➢ Radiation protection aspects related to the risk of secondary cancer following proton therapy
- Collaboration with Skandion Clinic (Uppsala):
Radiation Interaction in Media
CRT Development of fast and precise calculation tools for innovative treatment planning Development of radiation detector models for ion radiation, for better dosimetry
Radiation Protection
From anthropomorphic phantoms to patients
Secondary doses to healthy tissues from radiotherapy and modern imaging techniques => Risk of secondary cancer CRT IMRT
Radiation Protection
Dosimetric approaches for protection of people in large-scale nuclear emergencies CRT IMRT
Area where the effective dose exceeds 20 µSv in a time interval of 120 minutes after the event of an explosion involving Ir-192 sources.
