VIENNA - What's a medical physicist's take on CT dose reduction? To find out, we asked Mats Danielsson, PhD, professor and head of the research group in medical imaging at the Royal Institute of Technology in Stockholm and director for the Center for Life Sciences Imaging at KTH-Karolinska. In an interview with AuntMinnieEurope.com Editor-in-Chief Philip Ward at ECR 2016, he also speaks about the Karolinska, following the recent case of alleged fraud.

The CT image is shown in the axial plane. The PMV is automatically extracted using the developed deep learning model and overlayed onto the lungs for visual clarity.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/03/genkin.25LqljVF0y.jpg?auto=format%2Ccompress&crop=focalpoint&dpr=2&fit=crop&h=167&q=70&w=250)
