Magnus Båth is Associate Professor in Radiation Physics at University of Gothenburg and Senior Medical Physicist at Sahlgrenska University Hospital. He specialises in research related to optimisation of medical imaging. Within this field his research interests include development of methods for observer performance studies and image detector evaluations, the limitations of projection radiography and evaluation of image quality. A recent research interest concerns the introduction of tomosynthesis in healthcare and its effect on diagnostics, patient radiation doses and education of medical expertise.
Båth is currently engaged in several studies related to optimisation of medical imaging, mainly in the following three projects:
