I am a medical physicist from the Netherlands working in the field of medical imaging (radiology and nuclear imaging) as well as medical technology in general (e.g. everything used in the OR). For MSF I work with the diagnostic imaging working group (DIWG), led by Arlene Chua. I have developed tools for radiation safety assessment (a priori) and radiation monitoring of X-ray sites. Currently, my main focus is standardizing image dose and quality for MSF systems world-wide and portable X-ray systems for TB-screening.
