Breast cancer care starts with

• A policy of breast care • Finding (small) cancers

• Treating the malignant cancers • Embrace the women to completely recover from cancer

Radiological imaging of the breast

• 2D mammography • Magview imaging • Ultrasund • MRI • Breast tomosynthesis • Synthetic 2D • Breast CT • Contrast enhanced spectral mammography • Photon counting spectral imaging

New breast imaging approaches

Role of the medical physicist

• Understand • Simulate, design, predict, study, … grasp it

• Measure

• Establish a method, verify, robustness test, … get it

• Improve

• from understanding & measuring…

We simulate to understand the whole chain

We measure

We verify

We improve and prove it

Finally, we document the doses

The medical physicist in breast imaging, 2017

Helps decide between the different options Creates evidence for the choices Teaches and explains Initiates proper breast care and QA in order to • to reduce breast cancer mortality • to avoid over diagnosis • to ensure true breast care in the whole wide world

Medical physicists to spread the messages

• that breast care is important • that imaging is useful • that radiation risks can be under control • that women deserve good care We have the ethical obligation to communicate all this also to the public.

Thank you, Marie !
